Subs::NominalPointing (version 3.1)

Determine the mean pointing for the observation. This subroutine first merges all attitude files into a single file. It then runs the aspect FTOOL to calculate the mean pointing. It applies an instrument to spacecraft mean alignment file if there is one. The result is a set of Euler angles giving the mean spacecraft orientation, and a set of RA, Dec and Roll giving the mean instrument pointing as offset by the alignment file. The subroutine next calculates the galactic coordinates corresponding to the mean instrument RA, Dec and Roll. All of this information is logged and stored in the job.par file.
