Vela-Carina Archive

Vela-Carina is the fourth in a series of large area projects to map selected regions of the Galactic plane using the Spitzer Space Telescope Infrared Array Camera (IRAC). The Vela-Carina project (PID=40791) (Majewski et al. 2007, Zasowski et al. 2009) extended GLIMPSE-style coverage (two 1.2 second integrations at each position) to Galactic longitudes 255◦< l < 295◦ covering 86 square degrees of the Carina and Vela regions of the Galactic plane.\n\nThe Vela-Carina Archive (VelaCarA 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 information provided is in the same format as the Catalog. The 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.
