icbdist prints the mean spectral angle mapper (SAM) between two image-cube files, icbfile1 and icbfile2, to stdout. icbfile1 and icbfile2 are both ICB-format files.
If the option -vo is specified, then icbdist prints a terse output, consisting of only the value of the mean SAM, to stdout.
The mean SAM is calculated, in degrees, via a call to QccHYPImageCubeMeanSAM(3) .
