Hi

I'm trying to access the ENVI-based spectral angle mapper function
within IDL. I found the following function call definition:

ENVI_IDENTIFY_SAM_SETUP wl ref spec_lib handles NUM_SPEC

I assume wl represents the wavelength (range??), ref is the input
image, and spec_lib is the .sli file. I'm not sure what handles and
NUM_SPEC are, althoug the latter is optional (?).

Any help would be much appreciated.
