Detrended CTI

CTI analysis is now computed with "detrending":
Detrend CTI = Measured CTI + S3 amplitude reject rate * Detrend factor.

Average of ACIS-I CCDs (MnKa) slope 8.839e-9 CTI/day
Detrended slope 9.086e-9 CTI/day

ACIS Warm Pixels

A new algorithm for detecting bad pixels/columns is now in place.

A bad pixel was selected as follows:

acis*bias0.fits in a given period are obtained
compute an average of count rates for each ccd
compare each pixel to the average, and if a pixel value is 5 sigma higher than the average, a local average (32x32) is computed.
if the pixel value is still 5 sigma higher than the local average, it is marked as a possible warm pixel candidate.
if three consecutive bias frames have the same pixel marked as a warm pixel candidate, the pixel is listed as a warm pixel.
if the pixel is located at the edge of the CCD (y = 1023, 1024), it is dropped from the list.
for a hot pixel, a process is the same, except the threshold is the ccd average plus 1000 counts

A bad column is selected as follows:

each column is averaged, and compared to an average for the entire ccd.
if the average of the column is 5 sigma higher than the average of the ccd, compare the column average to a local average (10 columns).
if the column is still 5 sigma higher than the local average, mark it as a bad column candidate
if the column appears as a bad column for 3 consecutive frames, it is marked as a real bad column.
the columns: 258, 514, 770 appear regularly, but these are due to boundaries of the ccds and are not reported here.
