First Look Survey - Galactic Component

Principal Investigator: Tom Soifer

Science Category: galactic structure 
 Observing Modes: IracMap MipsScan 
  Hours Approved: 35.7 

Abstract:
The galactic component of the SIRTF First Look Survey is intended to
characterize diffuse emission and point source confusion at a variety
of galactic latitudes and in a typical molecular cloud.  The strategy
involves sparse mapping in 15 arcmin x 1 degree strips with MIPS and
IRAC along galactic longitudes 105.6 (galactic latitudes -1.3,0.35,
2.0,4.0,8.0,16.0, and 32.0  degrees) and 254.4 degrees (galactic
latitudes 0.0,-2.0,-5.0,-9.0, and -14.0  degrees).  In addition, four
small IRAC maps at galactic longitude 97.5 (galactic latitudes
0,-4,+4, and +16) will be made to best sample the stellar density of
the Galactic disk.  The L1228 molecular cloud will be mapped with a 10
arcmin x 2 degree strip with MIPS and IRAC.
