The antenna position fitting task BEE also lists antenna positions in both equatorial and topocentric coordinates.

      Although LISTOBS is formally carma specific, I must guess it's either
      working for SMA data, or with a trivial change can be made to work
      for it.

      At the top of listobs you would see the following type of information.
      The output of uvlist of the 'antpos' variable is fairly useless, as it's
      in nsec and in the XYZ (equatorial) coordinate system, and we're
      not used to think of it that way. Hence my conversion in listobs to
      the ENU format.
      You can also look at the python script in $MIRCAT/baselines/carma/xyz2enu.py
      which hopefully does the same.
