Why do some bright sources not appear in GLIMPSE catalogs?
Posted by Justin Howell on 02 April 2013 05:24 PM

The GLIMPSE Catalogs null any sources that are bright enough to be in danger of nonlinear detector response. The GLIMPSE Archives list the best fluxes that can be measured from such sources despite the nonlinearity.

Note that the Vizier version of the GLIMPSE catalogs uses the Catalogs, not the Archives.

For more details on the construction of the GLIMPSE catalogs, see the Column Descriptions and the Documentation.
