The position section is described in the
Table . Note that the source position is described
as the offsets between the actual (reconstructed) position (RA
or longitude, DEC or latitude) and the nominal
(commanded) position (RA_NOM, DEC_NOM). This also means
that for Solar System Objects (SSO), the offsets are not expressed in
the comoving frame, but from a fixed position on sky.
