SPECTRUM I [J [K]]
Extract a spectrum from an image according to the following numbering:
Spectrum (l) = Image (l,i,j,k)
for a 4-dimensional image. The spectrum is loaded into the X,Y buffers
of GreG. It can be processed later by the standard commands LIMITS, CON-
NECT, CURVE and so on.
The alternate syntax, used if any option is present, computes in the
output variable OutSpec a mean or integrated spectrum over the specified
region of the input Image variable InCube, using the current Greg poly-
gon and the specified Mask if any.
