A.C.Raugh: Final fix-up for archiving, including:
- updated schema references
- corrected field_location and field_length for all fields after 2
- added field_format for field 2 (utc)
- inserted unknown_constant for fields 8-9, 11-17
- inserted additional description for field 18 for lack of invalid constant
- removed ',' from associated .tab file

%5d
Integer counter of the number of star fixes executed by the star tracker. Used as a
reference for the validity of the pointing information. If the starfix is zero then
the telescope position is not known and the rest of the pointing information should
be ignored.
Note that this number is zero-padded on the left.
