Hi All,
        does anybody have a trick to make MIDAS plot the histogram of a
FITS
frame?

        Cheers

We have to execute the command STATISTICS/IMAGE first,
since the descriptor HISTOGRAM does not exist
frame: toto0001.mt  (data = UI2, format = FITS)
complete area of frame
minimum, maximum:                  1.479000e+03    3.509800e+04
at pixel (164,190),(114,319)
mean, standard_deviation:          2.364639e+03    1.394608e+02
3rd + 4th moment:                       119.684        21318.4

total no. of bins, binsize:             256      1.318392e+02
# of pixels used = 262144 from 1,1 to 512,512 (in pixels)
(ERR) SCDRDx: toto0001.mt + HIST_BINS - DSCNPR
(ERR) MID_ACCFRM: - VERNOR
Descriptor not present: Descriptor with given name does not exist for
given frame or may exist with a different data type.
