This data set presents tables 1, 2, 3, 4, 5 and 7 of 'Sizes, Shapes, Albedos, and Colors of Cometary Nuclei' (Lamy et al., 2004), and includes references for the sources cited. The authors culled this data from published or well-known unpublished sources, and have indicated what they judge to be the most reliable value available.

20 Oct 2008, A.C.Raugh AddedThis dataset presents several data tables from A'Hearn et al. (1995) [AHEARNETAL1995], which contain a comparative analysis of Haser model production for the observations included in the Lowell Observatory Cometary Database (LOCD). In addition, similar data for two more comets, West (1975 A1-A) and Kohoutek (1973 E1), are included.

The database presented here is comprised entirely of observations made utilizing conventional photoelectric photometers and narrowband filters isolating 5 emission species (OH, NH, CN, C3 and C2) and continua. This work was initiated by A'Hearn and Millis in 1976 and includes 2020 observations of 85 comets obtained over 429 nights through the end of 1992. The total number of observations, however, is not evenly distributed over the 85 comets. The median number of observations for a comet is 6, with only a single observation obtained for 14 comets while there were 820 observations of P/Halley. The majority of observations were obtained at either Lowell Observatory or Perth Observatory, however four other observatories were used including an extensive campaign on comet P/Halley from the Cerro Tololo Interamerican Observatory (CTIO). In this archive, results for a subset of 68 comets are presented while the results for P/Halley from this study are archived in the IHW archive.

The NEAR NUCLEUS STUDIES Network contains 2204 observations of Comet Halley spanning dates from 11982 Oct 16 through 1989 Apr 12.

The data set consists of ground-based images of comet 19P/Borrelly in the R filter taken at the Kitt Peak 2.1m for three nights from September 21-23, 2001, bracketing the Deep Space 1 encounter. Raw, as well as reduced images are included.
