These are pre-launch
estimates based on numbers available in March 2003.
- These are all "high" background estimates.
- The MIPS estimate is for 10 scan legs.
- 5 sigma point source sensitivity for IRAC 4 bands
(now is 48 sec only) [3,4,5,8]: 0.020, 0.025, 0.070, 0.100 mJy
- For MIPS fast scans [24,70,160]: 0.620, 3.865, 31.4 mJy
- For MIPS medium scan (cirrus) [24,70,160]: 0.225, 2.46, 28.9 mJy
(point source)
- For MIPS medium scan (cirrus) the 1 sigma extended source
sensitivity is estimated to be [24,70,160]: 0.0783, 0.0433, 0.145
MJy/ster
- MIPS is very sensitive! All of the 24 um images will probably be
unsaturated (except for occasional point sources). At 160 microns, the
position most likely not to saturate is the high-latitude cirrus
position. At 70 microns:
- some of L1228 will be OK (i.e., not saturated).
- 105: +8,+16, and +32 will be OK.
- 254: mostly unsaturated (except for point srcs) [and for
160 microns, the -9 and -14 latitudes will probably be fine
too]
