RE: [pyngl-talk] Problems opening CloudSat HDF-EOS files

Eric,

Yes, this fix will let you extract the gelocation data, as long
as you open the file with the ".hdfeos" extension. The variables
will be "Latitude_1B_CPR" and "Longitude_1B_CPR". I'm building you
a new version now, and will contact you offline when it's ready.
