These directories contain movies of the data from the HI
imager, part of the SECCHI package on the STEREO spacecraft.

The images have been corrected for the effects of having no
shutter and the majority of the blooming caused by saturated
pixels has been removed by interpolating over the saturated
columns.

The movies in the month directory are composites of the daily
movies in the subdirectories below.

The movies with a diff suffix are formed by doing a running
difference through all the days images.  Those without that
suffix have a daily minima subtracted to remove the f-corona.

Normally the movies have a linear auto contrast set to 5-95%
of the dynamic range of the data.  Those with the _e suffix
are histogram equalised within the same range.
