todo
** properly read the newmat file (don't use fscanf-- spaces between numers
are not guaranteed)
** "success" is indicated by existence of NEWMAT file written by mosflm.
Better to interact with mosflm directly in order to somehow verify success.
** investigate how these keywords affect mosflms behavior:
MOSAICITY
DISPERSION
DIVERGENCE
POLARISATION
POSTREF BEAM
POSTREF USEBEAM OFF
PREREFINE ON
EXTRA ON
POSTREF ON
These did not seem to affect the results by my (Rick's) experience, probably
because they are only used conjunction with image intensity data, but it's
worth another look at the documentation.
