#121 fixed Azatm -cuo option seemingly not working benj benj

If you use the -cuo option in azatm to change the values it's supposed to set overflowed and underflowed pixels to, it doesn't seem to have an effect - always sets underflowed pixels to 0 (even if told to set them to ffff) and always says:

************* radcal underflow and overflow fill values changed ********
      under : 00000  = 0     over: 00000  = 0 azatm output, regardless of what values are entered for the under/overflow (tried with 0 fffe and ffff ffff).

Arose from testing on #115

#44 fixed azgcorr 7-point Bursa-Wolff datum transformations not working correctly mggr mggr

From Chris Hecker (support ticket #42):

Since all our datasets are in ED50, I was trying in a next step, to get
that working. However, azgcorr seems to have troubles with the -d7
option. I use the following statement (without DEM at the moment):

azgcorr -1 h153131b.hdf -3 h153131b_out_noDEM_ED50.hdf -BIout \
-d7 0 -87 -98 -121 0 0 0 0 -mUTMZ 30 \
-in -p 2 2 -bl 100 -1 \
-v > h153131b_out_noDEM_ED50.txt

This should give me UTM Zone 30 for ED50 mean. However, the -v output to
the txt file shows that it uses Datum Shift type "Dutch" which is made
for RD reference system (not UTM at all) with Bessel ellipsoid etc, so
something different.

Confirmed this does the same for me, example output:

azgcorr  -- ver: 4.8.3-lin Jun 12 2007   (C) Azimuth Systems UK 1996, 2007

Note: NO DEM is being used which means that if significant topographic
      variation is present the geocorrected image will be unsuitable for
      accurate georeferencing against map or vector data or for mosaicing
      with adjacent lines, see User Guide for more details

Contacting Bill to see if this is a misuse/misunderstanding on our part or a bug in the option-reading/display code.

#194 fixed Azgcorr ENVI header issues (Support: Karl Hennermann, GB08/20) benj benj

Karl reports that if he geocorrects his data using azgcorr, any ENVI header file generated (either automatically because the file size went over the HDF limit, or manually using azexhdf -Be) reports the projection as UTM zone 30. I have duplicated the problem using one of the boresight flights, will contact Bill about it.
