Notes on datmovie:
==================
In order for datmovie to work smoothly it is recommended to have
the following environment variables set in DOS:
set TZ=GMT0
set FONTS=C:\FAIS or wherever you have the *.fon files.

and optionally:
set datadir=c:\fais\data or wherever you have the data.

There is no guarantee that datmovie gives the correct skymaps or the 
correct colours for the two polariyed modes. This depends on the antenna
configuration being used which may vary.
