FITS keywords

As a more continuous task we have been working on improving the FITS keyword information provided in the observing data. Several upgrades have been included in the new acquisition software connected to the new detector controller for ALFOSC. The keywords can now provide a complete description of any given exposure. The next step is to define how to use these keywords in practise (both how to fill them with the correct values, and how to use these values in the processing of a data file).

The interface for the FITS header archive has been improved to provide the principle header information as default.
