GLIMPSE II Archive

Metadata Updated: September 19, 2025

The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSEII) imaged longitudes ±10◦ of the central region of the Galaxy. The latitude coverage is ±1◦ from |l| =10◦to 5◦, ±1.5◦ from |l| =5◦to 2◦, and ±2◦ from |l| =2◦to 0◦. GLIMPSEII coverage excludes the Galactic center region l=±1◦, b=±0.75◦ observed by the GALCEN GO program (PID=3677). GLIMPSEII had two-epoch coverage for a total of three visits on the sky. The observations consisted of two 1.2 second integrations at each position in the first epoch of data taking (September 2005) and a single 1.2 second integration at each position six months later (April 2006).The GLIMPSEII Archive (GLMIIA or the “Archive”) consists of point sources with a signal- to-noise > 5 in at least one band and less stringent selection critera than the Catalog. The photometric uncertainty is typically < 0.3 mag. The GLIMPSEII Catalog is a subset of the Archive, but note that 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.
