Over the weekend I made a start on upgrading MSTATS to support CCDPACK
statistics, and NDF blocking to reduce the maximum memory demands. It
would be somewhat quicker though to just use an additional routine in
MSTATS to form the sum to solve Andy's immediate problem. It did alarm
me to see a subroutine call for every pixel in the existing code. It
will be interesting to compare performance of the two versions when the
job's completed.
