Incorrect physical and world coordinates in the output

If the lower limits in the bin parameter are set to anything other than 1 - i.e. xlo:xhi:xbin,ylo:yhi:ybin where xlo and/or ylo do not equal 1 - dmregrid fails to update the physical-to-logical coordinate system, which causes both physical and world coordinates to be incorrect in the output file.

Open-ended binning intervals do not work.  (28 Dec 2009)

The tool will fail if you provide open-ended intervals for the x binning, e.g. "::5,::5".

# dmregrid (CIAO): ERROR: Could not parse maxx string ':5,'

If the x-binning endpoints are provided but y endpoints are left open-ended, e.g. "1:1000:5,::5", the tool fails silently. The output file has no y-dimension:
