The data from this instrument consists of sets of measurements of Xray intensity as a function of diffraction angle. Almost all of it is collected using a position-sensitive detector (PSD), and is stored in CIF format.

These datasets are the high-resolution data collected at the APS 11-BM synchrotron beamline, and used to certify the microstructural characteristics of the two components (15 nm and 60 nm nominal microscrystallites) of SRM 1979. They are presented as CIF files containing the data as collected and processed by the 11BM software to make uniformly-spaced angle step data files. Each CIF contains the 'raw' data from 11BM, the same data with an angular scale corrected by refinement of SRM660c data collected in the same run, and finally a computed data set from a Rietveld structural fit to the results. There are 9 CIF files in the ZIP archive. Each file is names xxxx_yy_nm_zzz.cif where xxxx is the run number at APS under which the data were collected, yy is either 15 or 60 for the nominal crystallite size, and zzz is the bottle number form the random sampling of the SRM used to take this measurement.

The data from this instrument consists of sets of measurements of Xray intensity as a function of diffraction angle. All of it is collected and is stored in JSON files. The files are highly self-descriptive of their content, and contain angles, intensities, temperatures, and other environmental parameters, along with metadata.

This dataset contains X-ray diffraction (XRD) results for coal samples from the Usibelli Coal Mine and fly ash samples from the Atkinson Heat and Power Plant in Fairbanks, AK. Additionally, X-ray diffraction results from the solid phase residuals of leaching experiments with the same fly ash are reported. The leaching experiments were performed with either 18 mega-ohm or simulated rainwater for up to 90 days and XRD was performed on solid phase residuals from sacrifical timepoints (1 hour, 2 days, 7 days, 14 days, 28 days, and 90 days).

**Subject Area:** Astronomical data **Description:** The Sloan Digital Sky Survey (SDSS) is a multi-organization effort to gather deep, multi-color images covering more than a quarter of the sky and create 3-dimensional maps of celestial objects. The data is released annually to the general public as data releases (DR)'s. The SDSS used a dedicated 2.5-meter telescope at Apache Point Observatory, New Mexico, equipped with two powerful special-purpose instruments. The 120-megapixel camera imaged 1.5 square degrees of sky at a time, about eight times the area of the full moon. A pair of spectrographs fed by optical fibers measured spectra of (and hence distances to) more than 600 galaxies and quasars in a single observation. A custom-designed set of software pipelines kept pace with the enormous data flow from the telescope. The data set and more info can be found at http://cas.sdss.org/astrodr6/en/.

Energy dispersive X-ray spectroscopy (EDX) tomographic tilt series of a needle-shaped sample extracted from NIST SRM 2135c.Sample description: This SRM consists of alternating layers of nickel and chromium on a silicon substrate (see SRM certificate for further detail).Data description. The scan size for each spectrum image (SI) is 128 pixels x 100 pixels and 4000 spectral channels deep. EDX data were collected using the following parameters:Beam energy (keV): 300.0Probe current: 0.5 nAPixel size: 3.0 nmDwell time per pixel: 200 msecEnergy resolution: 10 eV/channelThe SI's were collected over a 180 degree range of specimen tilts with a 5 degree tilt step between each acquisition.
