I've converted some of David's .txt files to FITS files:
Results_MS100/data_cube.txt has been converted to
ftp://ftp-glast.slac.stanford.edu/glast.u06/jchiang/SAMSI/dvd/ms100_data_cube.fits
This data cube can be viewed as a movie using ds9.
The average of the 50 frames in this cube is in
ftp://ftp-glast.slac.stanford.edu/glast.u06/jchiang/SAMSI/dvd/ms100_avg.fits
and
Results_MS_prior_sensativity/spun-*.txt have been converted to
ftp://ftp-glast.slac.stanford.edu/glast.u06/jchiang/SAMSI/dvd/spun-*.fits
