File: /outgoing/iris_patches/8.01/README801

This is a summary of the IRIS 8.01 patches available on the SIGMET
ftp site.  File last updated 29 April 2004.  The general proceedure
for installing patches is:
 1) Move the file platform/foo.gz.v# to your IRIS_BIN directory and rename
    the file so that it no longer contains ".v#" (e.g. mv foo.gz.v# foo.gz)
 2) Rename the file it will replace (e.g. "mv foo foo.old" )
 3) Uncompress the new file (e.g "gunzip foo.gz")
 4) Set ownership and mode to exactly match the old file
    (e.g. "chown operator foo", "chgrp users foo", "chmod 775 foo")

output.gz.v12
The output process had a open file leak: Every time the IRIS
overlay image was drawn using the new GIF underlay feature,
the GIF file was opened but not closed.  This caused a failure
when the OS open file limit was exceeded.  This limit is 200
on SGI workstations, and 1024 on Linux workstations.

product.v12.gz
Fixes bugs in cartesian product generation for some of the
new projections.  Unnamed Gnomonic projections failed
to run.  Named Gnomonic and Perspective projections were forcing
the reference latitude to the equator.  This was serious for
Gnomonic, but not so serious for Perspective since geosynchronous
satellites are over the equator usually.
