Read THEMIS all-sky imager ASI data

THEMIS uses the CDF (Common Data Format) for many L1 data products.

CDF is NOT the same as NetCDF, so programs such as ncBrowse and ncview will NOT work with Themis CDF files.

Download THEMIS L1 CDF file by first looking at the L0 64x64 pixel GIF previews.

Matlab and Python functions for THEMIS ASI images make movies and the like.
