Completing the Spitzer Galactic Plane Survey
A Spitzer Cycle 6 Exploration Science Program
GLIMPSE360 gaps proposal
99.99% of the data have been taken.
Observations started September 2009 and will hopefully conclude at the end of 2012.
Source lists were delivered to IRSA for l=109.0-169.0 deg and will be available at IRSA
GLIMPSE360 Areal Coverage
MSX 8 micron image of the Outer Galactic plane from Price et al. 2001. The
survey limits are shown with solid red lines and are based on the midplane of the CO/HI warp at a
Galactocentric radius of 13 kpc (Binney & Merrifield 1998); the dashed line shows the position of
the warp at 14 kpc. The filled circles show the mean latitude of red IRAS sources, binned by 10 deg in
longitude. Rectangular boxes show regions previously observed with IRAC. In the small programs,
the exact orientation of the observing strip is not shown, and is placed vertically on the figure.
The Galactic Plane showing the areas covered by previous surveys in white and the
GLIMPSE360 survey in blue. The circles centered on the Sun shows the GLIMPSE360 detection limit
distance for a solar type star (solid line) is about twice that of WISE (dashed line). The approximate
positions of Galactic spiral arms (Taylor & Cordes 1993) are indicated in red. The dashed spiral
arms have tangency points that show no excess star counts (Benjamin 2007) and may not be
density wave arms. The central oval and bar represent the approximate extent of the central
triaxial bulge/bar (Gerhard 2002; Cole & Weinberg 2002) and the Long bar (Hammersley et
al. 2001; Benjamin et al. 2005). The radius marking the expected truncation or break in the
exponential Galactic stellar disk is also shown with a dashed line.
GLIMPSE360 AORs (1468 AORs)
Scheduled are 264,804 pointings x 2 bands per pointing x 2 FTs (HDR mode) = 1,059,216 frames
GLIMPSE,GLIMPSEII,GLIMPSE3D areal coverage
COBE/DIRBE 4.9 um map of infrared intensity in the Galactic plane. The dotted lines show the area
already observed by GLIMPSEI and GLIMPSEII. The vertical extensions for GLIMPSE3D are shown with
