Deep GLIMPSE is the sixth in a series of large area projects to map regions of the Galactic plane using the Spitzer Space Telescope Infrared Array Camera (IRAC). Deep GLIMPSE is a Warm Mission Spitzer Cycle 8 Exploration Science Program (PIDs 80074 and 80253) that mapped 125 degrees of longitude of the Far Side of the Galaxy. Warm Mission Spitzer has two IRAC bands, centered at approximately 3.6 and 4.5 μm. The Galactic longitudes covered by Deep GLIMPSE are l=265◦-350◦and 25◦-65◦. The latitude width is about 2.1◦. The latitude center follows the Galactic warp at a Galactocentric distance of 13 kpc to survey the Far Outer Galaxy.The Deep GLIMPSE Archive (GLMDPA or the “Archive”) consists of point sources with less stringent selection critera than the Catalog. The information provided is in the same format as the Catalog. The Catalog is a subset of the Archive, but the entries for a particular source might not be the same due to additional nulling of magnitudes in the Catalog because of the more stringent requirements.
