We have observed 2 degrees (1 leg) in fast mode for three different regions of
the sky (zodi_13a, zodi_13b, and zodi28b). Note that two of
the 160micron SCAN regions were observed in MIPS-914 and MIPS-915.
Since these tasks are repeated a number of times during IOC, we will observe
different regions of the sky each time. The tasks will check for possible
variations of quality of IC or saturation. This task will also be useful for
screening regions of the sky to obtain ICs in SIRTF routine operations.
The reduction was performed with the DAT programs. We used mips_sloper with
sensitive cosmic ray detection (-q option)
turning off the electronic non-linearity correction, mips_caler (using
the 160micron me_160_dark_CamO_1_3nov2003.fits)
and mips_enhancer with the following options:
verbose = 0
scale = 1.
filename = ic160_scan
prefix = ic_scan160
nXTile = 1
nYTile = 1
dark = 0
flat = 0
illumination_correction = 1
NormalizeInput = 1
SigmaCut = 3.0
SigmaTolerance = 0.25
MaxIterations = 10
StackSTDEV = 0
OutlierMinPoints = 3
QuartileFactor = 10
OverlapTolerance = 0.5
diagonistics = 1
WriteGeometry = 0
WriteOutlier = 0
WriteTiles = 0
FluxMean = 0
FluxMedian = 1
OverWrite = 1
distortion = 0
UseBoostFrame = 1
reject = 1
Note that we rejected the first DCE after the stim flash (reject = 1 option) and normalized
the input images (NormalizeInput = 1 option).
