GLIMPSE II Epoch2 More Reliable Archive

Metadata Updated: April 10, 2026

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).\n\nThe GLIMPSEII Epoch 2 More Reliable Archive (GLMIIEp2MRA) consists of higher reliability point sources than the Archive. It was produced for the single visit epoch 2 only source lists to provide a higher reliability source list than the Archive. No highly reliable Catalog is produced for this dataset since it requires a source be detected twice in one band. The sources in the More Reliable Archive have the same stringent criteria as the Catalog except two detections are not required in a single band. Two detections in adjacent bands are required (the “1” can include the 2MASS Ks band); for example one detection in band 1 and one detection in band 2.
