To convert the IMG files to FITS format, everything has been 
automated.  To add or remove items during the lien resolution process,
correct the files listed here to make the changes.


SCRIPT

While in the CODE directory:

Run TFRELABEL to generate new PDS labels that allow PDSREAD to read in
the overscan regions, if they exist.  (For windowed images, they are
included, but are set to 0)

Run TFREFORM to generate the  FITS header files and the label files
for the FITS images.  

Run IDL routine SDU_FLIP, which uses READPDS to read in the images
(using the new detached headers), grabs the corresponding FITS header,
and writes them out to FITS files in the data directory.  

Check to make sure that the number of FITS images matches the number of
original IMG images.  Check the file nowrite.lst to see if any files
were not written and why.

Use the file DISPLAY_CHECK (IDL script) to display all the files and
make sure there are none that have offset columns (diagonal across the
screen) 

Run REDIST to redistribute the files into subdirectories.



To create index files:

./pdsidx -n -r -d ../data -f keys.lst -r -o ../index/index.tab

format the indewx file using TFINDEX_FORMAT
Check the new file INDEX_NEW.TAB with respect to the label, then
rename it to INDEX.TAB


Verify the different labels etc. using VC_CHECK


To create the download directories and the checksums, use SUM_ZIP
