The central 2.0 by 1.4 degrees of the Milky Way Galaxy was surveyed by the Spitzer Space Telescope's IRAC instrument at mid-infrared wavelengths. A catalog of 1,065,565 point sources was produced, providing magnitudes at 3.6, 4.5, 5.8, and 8.0 microns, supplemented by JHK photometry from the 2MASS survey. These data, from NASA's Cycle 1 program GO 3677, represent the highest spatial resolution and sensitivity uniform large-scale map of the region at the time.
The YSOVAR Spitzer Space Telescope program provides mid-infrared time series photometry for star-forming regions including the Orion Nebula Cluster and 11 other cores. It contains light curves for approximately 29,000 unique objects, captured at 3.6 and 4.5 micron wavelengths. The data is from NASA, with initial results published in 2011 and detailed conventions described in 2014.
The Guide Star Catalog II (GSC-II) is an all-sky optical catalog based on 1" resolution scans of photographic Sky Survey plates from the Palomar and UK Schmidt telescopes. It contains positions, proper motions, classifications, and magnitudes for nearly a billion objects down to approximately Jpg=21, Fpg=20. The catalog is maintained by the National Aeronautics and Space Administration and is used for Hubble Space Telescope operations and will support the James Webb Space Telescope.
