GLIMPSE Observation Strategy Validation

Time will be scheduled during early SIRTF operations to validate our observing strategy (OSV). The GLIMPSE OSV region is chosen to sample a range of stellar densities and diffuse background levels characteristic of the inner Galactic plane. The observations will probably take place in late December 2003.

With the SIRTF launch date of August 25, 2003, the GLIMPSE OSV target is RCW49:

The OSV will consist of four 1 deg x 0.17 deg AORs nearly identical to normal GLIMPSE AORs. These will be repeated with varying frame offsets (along the strip direction) and overlaps (between strips). The GLIMPSE OSV will also perform a single 2 deg x 0.17 deg AOR to allow the evaluation of the pointing reconstruction accuracy for the full half hour it takes to do a single diagonal band across the Galactic plane.
