0.7.7 (2008-12-13)
* (bug fix) error in calculation of characteristic energy fixed

0.7.6 (2008-12-06)
* output moments files can include characteristic energy

0.7.5.3 (2008-11-29)
* restructuring & tidying up of code, including improvements to the
  CDF/CEF reader

0.7.4.6 (2008-09-04)
* bug fix - moments were incorrect for HEEA completely overlapping
  LEEA situations, and sensor combinations involving 3DX data with
  energy windows.

0.7.4.5 (2008-09-01)
* CAA data download now works
* bug fix - checks if the file supplied by the CAA command-line
  interface is an error message or not

0.7.4.1 (2008-08-14)
* bug fix - FGM B-field wasn't rotated to SR2 or ISR2 when moments 
  were requested in this coordinate system
* more fixes & improvements for calculation of moments from PITCH_3D

0.7.4.0 (2008-07-24)
* bug fix - new S/C potential code was missing for 2nd PEACE data file
* added ability to calculate moments in the energy overlap region from
  PITCH_3D files

0.7.3 (2008-07-23)
* EFW L2 S/C potential can be used in moments plots
* bug fix - EFW L2 & L3 S/C potential files in CEF format now work

0.7.2 (2008-07-22)
* bug fix - when density and/or velocity is a fill value, the value for the
  current was the last real value, rather than a fill value.
* S/C potential code re-written (sync to PEACE data; interpolation etc)
* bug fix - S/C potential can now be included in output files (previously
  didn't work). Also included in .xml files (accidently left out before).
* fill values from EFW potential & FGM B-field files are now identified
  correctly.

0.7.1 (2008-07-18)
* coordinate system correct in current variable meta data
* fill values in Qpara, Qperp, Hpara, Hperp now correct
* loading of .xml files containing "Overlap 2-sec" sensor combination and/or
  "B-field aligned" now works
* in moments plot, units of current now correct in y-axis label

0.7.0 (2008-07-15)
* can calculate moments in the energy overlap region from PITCH_FULL with 2-sec
  time resolution
* energy overlap region part of spectrogram for PITCH_FULL can be plotted
  (preliminary version)
