NAME

X-GEN - analmr  

SYNOPSIS

analmr [-s] [minsig]  

DESCRIPTION

"analmr" reads in processing results from a MULTIREF that has been scaled, and prints a detector-position distribution chart for I/<I>. That is, for all observations with I/sigma greater than a cutoff and <I>/sigma greater than the same cutoff, it computes I/<I> and takes the mean of those values within a small geometrical region on the detector face. It then prints out the chart of those regions. If the "-s" option is specified, it writes out a modified USPLINE file containing the mean values to be used as sensitivity-correction values.

"analmr" is an alternative way of attempting to map differences in sensitivity across the detector face. The standard method is to use "qecor" to examine a flood-field and produce the sensitivity corrections based on that flood-field. If no flood-field image is available, "analmr" on a high-quality, heavily replicated data set may offer an alternative. It is likely to make things worse if the MULTIREF from which it is derived is either of low quality or is lightly replicated.

-s
If specified, we write out a modified USPLINE file containing the mean values to be used as sensitivity-correction values.
[minsigma]
Use only reflections with <I> / sigma greater than this value. The default value of this parameter is 1.
