[daip] FITS Antenna tables

[David Titterington]

Dear AIPS,

We are writing UV data from one of our instruments in FITS format for
import to AIPS, and need to add the antenna tables as an extension to
the FITS file, but I haven't so far been able to find a reference in
the documentation which will tell me the coordinate system expected
by AIPS for the antenna positions.

Could you point me in the right direction, please?

Many thanks,
