Observing Strategy:
 
    IRAC: 2 epochs, 2 dithers, 12 sec integration per exposure
	  one epoch in HDR mode, one epoch in full array mode
 
    MIPS: fast scan map, 2 epochs
	  125" cross-scan, 80" in-scan offset between epochs

Map2: 6.6

Comments:

The response patterns at both 70, 160 didn't correct well with self-flatting 
in the ICD data.  This is because the pixel responses change too fast within 
a scan leg.  The usual recommendation is that photometry should be done on 
the plain BCD (bright 70 and all 160) and the filtered BCD (faint 70). 

Significant muxbleed and associated pinstriping, along with column pull-down,
from bright stars is present in IRAC bands 1 and 2.
 
Optical banding around bright stars is present in IRAC bands 3 and 4.
 
Latent images from bright sources are not fully removed from the MIPS images.
False detections associated with these latent images have been removed from
the band-merged source catalog.
