The I_RGO.PS file has been corrected.

Separate CALINFO.TXT files were added to each of the subdirectories 
under the 'CALIB' directory. Included in these files are simple tables 
identifying the purpose and some additional information for each file 
in that subdirectory.

Yes. We expanded the DESCRIPTION keyword value in the label for each 
calibrated ISIS spectra to explicitly describe what was done.
