two significant changes:

1- in the averaging, before the data is finally written out, duplicate q-values (within 0.1%) are averaged so that duplicate q-values do not appear in the data file. This has a very bad effect on the calculation of the smearing matrix (dq=0).

2-for the data from the back (high res) detector, two steps have been added to the processing at the point where the data is converted to WORK. First, a constant read noise value of 200 cts/pixel is subtracted (found from average of multiple runs with beam off) Second, a 3x3 median filter is applied to the whole image to eliminate the stray bright pixels. Some are saturatd, some are simply outliers. Very effective.
