One of the features of the CFI instrument discovered during the
calibration was a fringing pattern found in filters 2 and 3. Examination of flat
field data acquired at varying temperature revealed that the pattern moved as
temperature varied. The results for Jan 2002 Filter 2 were redone in November of
2002 with an improved dark estimate derived from the dark columns integral to
the images (cfi_semical.html)
. The Jan 2002 Filter 3 data have the original less than optimal dark
correction.
