=== Q: My azgcorr has expired, where can I get a new one? ===

'''A:'''[[BR]]

Due to the regularity of updates and to enforce licensing constraints, azgcorr has an expiry date built into it.  If your azgcorr expires, you'll see a message like:
{{{
azgcorr  -- ver: 4.9.11-lin Jan 13 2009   (C) Azimuth Systems UK 1996, 2009

 ******************************************************
 TO:  mggr   using system  pmpc889.npm.ac.uk  with serial number ff88ed54
 ******************************************************
 ***  Warning: the licensed period of this program  ***
 ***  ended on:       22/02/2009     please contact ***

 ******************************************************
}}}

If you have an original distribution copy (i.e. you were PI on an ARSF flight), you should have login details for an FTP site containing updates.  If you have acquired your data via NEODC (or if you don't have these details), you'll need to contact us.  Please email us at ''[http://www.npm.ac.uk/email/?user=arsf-processing&sub=azgcorr+expired arsf-processing -at- pml.ac.uk]''.

Regrettably we cannot publish the login details on a public wiki.

=== Installation ===

Ensure you install the new azgcorr in the right place on your system.  When you run azgcorr, you should see a version line like:
{{{
azgcorr  -- ver: 4.9.18 May 27 2009   (C) Azimuth Systems UK 1996, 2009
}}}

If this version number doesn't match the one you downloaded, you're still running the old version. Try running "`which azgcorr`" to see where your current azgcorr is being run from, then replace that with the new one.

Alternatively, if you don't want to delete the old one or don't have access, you can run a specific version by putting the full path to the executable, e.g. "`/where/you/put/azgcorr.4918 -p 5 5 -1 c192a011b.hdf -3 c192a011b-3.hdf`"
