A further possibility if you have suitable data is
mstats <list of NDFs> smode=mean
then a CMULT by the number of NDFs. By suitable you must have no bad
pixels or bad pixels in the same locations through the NDFs, as the sum
will be less than the mean times the number of NDFs in the presence of
bad pixels.
One job on the KAPPA list is to extend MSTATS to support the full list
of estimators available in the likes of COLLAPSE.
