GLIMPSE360 Observations

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 shortly.

GLIMPSE360 Areal Coverage

[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.

[GLIMPSE360 areal coverage]
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


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 solid lines.
