20.22.17      SHORT_MODE

INTEGER code used for backward compatibility with an older version of the UV_SHORT task, and also for test purpose.

Allowed values are :

 -1  indicates to create a single UV table with columns for the Phase
     center offsets only
 -2  indicates to create a UV table with columns for the Pointing
     center offsets
 -3  indicates to create a UV table with the additional columns
     type being Pointing or Phase, as in the original UV_TABLE$
 -4  Allow to override the antenna diameter in the Telescope section
 +1  indicates to append to the initial UV table the short spacings
     with Phase center offsets (which must thus match the initial UV
     table shape)
 +2  indicates to append to the initial UV table the short spacings
     with Pointing center offsets (which must thus match the initial
     UV table shape)
 +3  indicates to append to the initial UV table the short spacings
     (The extra column type being determined automatically).
 +4  Allow to override the antenna diameter in the Telescope section

The default value is 3, i.e. automatic merging with the current UV table.
