Isis ISIS Spectral Libraries

----

The following are SPECPR format spectral libraries that are included in $ISISDATA. These can be used as input to the "specpr2isl" program to produce ISIS Instrument Spectral Library (ISL) files. Note that these data files are currently available only on the Solaris and SGI platforms because the SPECPR format files are only available for this hardware architecture (byte ordering).

The following is a JPL SPAM format spectral library that is included in $ISISDATA. This can be used as input to the "spam2isl" program to produce ISIS Instrument Spectral Library (ISL) files. Note that this data file is currently available only on the Solaris and SGI platforms because the SPAM format file is only available for this hardware architecture (byte ordering).

NOTE:

Running "specpr2isl" or "spam2isl" on the Solaris or SGI platform will produce a Solaris/SGI format ISL file. An ISL file is actually an ISIS cube file, and the "convert" program can be used to convert cube files to a different hardware architecture. However, "convert" cannot be used for converting an ISL file because the spectral header information is packed into a set of backplanes in the file. "convert" does not yet properly handle the conversion of the spectral header information in the backplanes.
