Merged Catalog of Reflection Nebulae
Several catalogs of reflection nebulae have been merged to create a uniform catalog of 913 objects. It contains revised coordinates, cross-identifications of nebulae and stars, as well as identifications with IRAS point sources. The HEASARC has endeavored to render all identifications of the nebulae in the various catalogs according to the styles recommended by the Dictionary of Nomenclature of Celestial Objects. This table was created by the HEASARC in October 2012 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/399/141">CDS Catalog J/A+A/399/141</a> file table1.dat.

Shakbazian Compact Groups of Galaxies
공공데이터포털
This catalog is a compilation of ten lists of compact groups of compact galaxies found on the Palomar Sky Survey red charts and published in the period 1973 to 1979 by Shakhbazian, Petrosian, and collaborators. The catalog contains 377 groups of compact galaxies and includes identifications, equatorial coordinates, numbers of constituent galaxies, magnitudes of the brightest member, sizes of the groups as a whole, and coefficients of relative compactness. The HEASARC has a related database table, SHKGALAXY, which contains data on the individual galaxies in the Shakhbazian Compact Groups. This database table was created by the HEASARC in December, 1999, based on the CDS catalog VII/89B. This is a service provided by NASA HEASARC .
CatalogofGalaxiesObservedbytheEinsteinObservatoryIPC&HRI
공공데이터포털
This is a catalog of galaxies observed in the X-ray band with the Einstein Observatory imaging instruments, the Imaging Proportional Counter (IPC) and the High Resolution Imager (HRI). The catalog comprises 716 observations of 493 galaxies, including those that were targets of pointed observations, and galaxies from the Revised Shapley-Ames (RSA) Catalog of Bright Galaxies and the Second Revised Catalog (RC2) Catalog of Bright Galaxies that were serendipitously included in Einstein fields, plus X-ray data on 4 other galaxies (LMC, SMC, M 31 = NGC 224, and M 32 = NGC 221) taken from the literature, for a total of 720 entries. A total of 450 of these galaxies were imaged well within the instrumental fields, resulting in 238 detections and 212 3-sigma upper limits. The other galaxies were either at the edge of the visible field of view or were confused with other X-ray sources. This database was created by the HEASARC in January 2002 based on CDS Catalog J/ApJS/80/531, tables gxatlas.dat and gxfluxes.dat. This is a service provided by NASA HEASARC .
Lynds Catalog of Dark Nebulae
공공데이터포털
This catalog is an updated version of the original version of the Lynds' Catalog of Dark Nebulae that was published in 1962. The catalog was based on a study of the red and blue prints of the National Geographic - Palomar Observatory Sky Atlas. The catalog contains positions for the centers of dark nebulae or clouds found by Lynds, values for the cloud sizes in square degrees, visual estimates of their opacity, and cross-identifications to Barnard Objects which are associated with the tabulated clouds. This HEASARC version of the LDN Catalog was created in June 1997. It was derived from CDS Catalog VII/7A obtained from https://cdsarc.cds.unistra.fr/ftp/cats/VII/7A/. Please refer to the CDS "Historical Notes" for details regarding the lineage of this version. Additional information provided in the HEASARC documentation was taken from the original published version of this catalog. This is a service provided by NASA HEASARC .
UVCet-typeFlareStars&RelatedObjectsCatalog
공공데이터포털
This table contains the catalog of the UV Cet-type flare stars and related objects in the solar vicinity. This new catalog of flare stars includes 463 objects. It contains astrometric, spectral and photometric data as well as information on the infrared, radio and X-ray properties and general stellar parameters. This table was created by the HEASARC in October 2005 based on the merger of 3 CDS tables (table1.dat, table2.dat and atble3.dat) from the CDS Catalog J/A+AS/139/555/ .

Ritter Binaries Related to CVs Catalog (7.21 Edition)
공공데이터포털
This HEASARC database table contains information on the so-called "Related Objects" only, as taken from the Catalog of Cataclysmic Binaries, Low-Mass X-ray Binaries, and Related Objects (7th Edition, Release 7.21, March 2014) of Ritter & Kolb. The complete catalog lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components, and other characteristic properties of 1166 cataclysmic binaries, 105 low-mass X-ray binaries, and 500 related objects with known or suspected orbital periods. The HEASARC has for simplicity split this catalog into three Browse database tables, one for each class of objects: the present table (RITTERRBIN) containing the related binaries' data, a second one (RITTERCV) containing cataclysmic binaries' data, and a third one (RITTERLMXB) containing the low-mass X-ray binaries' data. The literature published before 1 January 2014 has, as far as possible, been taken into account. Related objects are detached binaries consisting of either a white dwarf or a white dwarf precursor primary and of a low-mass secondary. The secondary may also be a highly evolved star. This table was last updated by the HEASARC in April 2014 based on the pcbdata.dat file from the CDS Catalog B/cb. This is a service provided by NASA HEASARC .
Shakhabazian (Shk) Compact Groups of Galaxies: Individual Galaxies Data
공공데이터포털
The largest survey of compact galaxy groups was published by Shakhbazian et al. (the CDS catalog VII/89, implemented by the HEASARC as the SHK database table). This present catalog provides accurate positions of the individual galaxies in the groups; photometric properties of the Southern sky (delta not greater than +2.5 degrees) are evaluated on the basis of the COSMOS/UKST catalog of the Southern sky. This catalog contains 373 groups; this number differs from the number in Shakhbazian's list (377 groups) by the following: (i) there are no data for groups 001 (already published by other authors), 206 and 241 (could not be re-identified), 252 (this is identical with 214), 301 and 353 (could not be re-identified); (ii) Group 328 was published twice (in North and South); and (iii) Group 340 was divided in two parts (340 and 340a), according to Bettoni and Fasano ([BF95]=1995AJ....109...32B). This HEASARC version of the catalog contains a total of 3435 individual galaxies identified as members of the compact groups, 2574 from the northern part of this survey (taken from the ADS Catalog VII/196 file north.dat), and 861 from the southern part of this survey (extracted from the 10746 entries in the ADS Catalog VII/196 file south.dat by including only entries corresponding to bona fide group members). This database table was created by the HEASARC in June, 2000, based on the CDS Catalog VII/196 (files north.dat and south.dat). This is a service provided by NASA HEASARC .
StarswithRotationPeriods&X-RayLuminositiesCatalog
공공데이터포털
This table contains photometric and derived stellar parameters for a sample of 820 solar and late-type stars (the original table of 824 entries had 4 near-duplicate entries for the stars HD 19668, HD 95188, HD 216803 and HD 285382 which have been removed by the HEASARC) from nearby open clusters and the field, including rotation periods and X-ray luminosities. This sample was used by the authors to study the relationship between rotation and stellar activity and derive a new estimate of the convective turnover time. From an unbiased subset of this sample the power law slope of the unsaturated regime, LX/Lbol ~ Robeta, is fit as beta = -2.70 +/- 0.13. This is inconsistent with the canonical beta = -2 slope to a confidence of 5 sigma, and argues for an additional term in the dynamo number equation. From a simple scaling analysis, this implies Delta(Omega)/Omega ~ Omega0.7, i.e. the differential rotation of solar-type stars gradually declines as they spin down. Super-saturation is observed for the fastest rotators in this sample and its parametric dependencies are explored. Significant correlations are found with both the corotation radius and the excess polar updraft, the latter theory providing a stronger dependence and being supported by other observations. The authors estimate mass-dependent empirical thresholds for saturation and super- saturation and map out three regimes of coronal emission. Late F-type stars are shown never to pass through the saturated regime, passing straight from super-saturated to unsaturated X-ray emission. The theoretical threshold for coronal stripping is shown to be significantly different from the empirical saturation threshold (Ro < 0.13), suggesting it is not responsible. Instead, the authors suggest that a different dynamo configuration is at work in stars with saturated coronal emission. This is supported by a correlation between the empirical saturation threshold and the time when stars transition between convective and interface sequences in rotational spin-down models. This table was created by the HEASARC in March 2012 based on CDS Catalog J/ApJ/743/48 file catalog.dat. The original table had 824 entries, including 4 near-duplicate entries for the stars HD 19668, HD 95188, HD 216803 and HD 285382, which have been removed by the HEASARC.

UVOT Bright Star Catalog
공공데이터포털
This catalog was compiled from 4 catalogs: Tycho-2, GVCS III, NGC, and the Yale Bright Star Catalog. All catalogs were preprocessed before compiling this catalog to achieve uniform columns and units. Next, they were merged into one catalogue before eliminating "red" objects and precessing all coordinates to epoch 2000.0. The catalog was then corrected for missing decimal points. Finally, the catalog was sorted by R.A. for ease of locating objects within the catalogue. The original catalog contained 239,853 objects brighter than 12.0 mags. This table was originally created by the HEASARC in July 2008 based on an input table supplied by the Swift Project which was compiled by Elizabeth Auden at MSSL. It was renamed to UVOTBSCAT in January 2009. This is a service provided by NASA HEASARC .
HerMES Band-merged Catalog (24 micron positions)
공공데이터포털
The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme (KPGT_soliver1) designed to map a set of nested fields totalling 380 sq. deg. Fields range in size from 0.01 to 20 sq. deg., using SPIRE at 250, 350 and 500 microns. These bands cover the peak of the redshifted thermal spectral energy distribution from interstellar dust and thus capture the reprocessed optical and ultraviolet radiation from star formation that has been absorbed by dust, and are critical for forming a complete multiwavelength understanding of galaxy formation and evolution.
Updated Nearby Galaxy Catalog
공공데이터포털
This table contains an all-sky catalog of 869 nearby galaxies having individual distance estimates within 11 Mpc or corrected radial velocities relative to the Local Group centroid VLG < 600 km s-1. The catalog is a renewed and expanded version of the previous Catalog of Neighboring Galaxies by Karachentsev et al. (2004, AJ, 127, 2031). It collects data on the following galaxy observables: angular diameters, apparent magnitudes in the far-UV, B, and Ks bands, H-alpha and H I fluxes, morphological types, H I-line widths, radial velocities, and distance estimates. In this Local Volume (LV) sample, 108 dwarf galaxies still remain without measured radial velocities. The catalog also lists calculated global galaxy parameters: the linear Holmberg diameters, absolute B magnitudes, surface brightnesses, H I masses, stellar masses estimated via K-band luminosity, H I rotational velocities corrected for galaxy inclination, indicative masses within the Holmberg radius, and three kinds of "tidal index" which quantify the local density environment. In the reference paper, the authors briefly discuss the Hubble flow within the LV and different scaling relations that characterize galaxy structure and global star formation in them. They also trace the behavior of the mean stellar mass density, H I-mass density, and star formation rate density within the volume considered. This table was created by the HEASARC in June 2013 based on electronic versions of Tables 1 and 2 from the reference paper which were obtained form the AJ web site.
