Abstract:
We propose one IRAC map and two MIPS scan maps to extend (and complete) our map
of W5. Previous MIPS observations (PID20300) just missed the deeply embedded
star formation on the eastern--most edge of the HII region. One of the proposed
MIPS observations will cover this region, matching our IRAC coverage. The second
MIPS AOR will fill a narrow gap in the middle of our map at 70 microns, enabling
us to complete our analysis of the dust emission in the bright rim surrounding
W5. The current gap unfortunately passes along a ridge of 70 micron emission,
where the two HII region bubble walls meet. The IRAC map covers the northeast
corner of the bright rim, completing our map.
