The antenna selection string is a semi-colon (’;’) separated list of baseline specifications. A baseline specification is of the form:

  • ’ANT1’ — Select all baselines including the antenna(s) specified by the selector ANT1.
  • ’ANT1&’ — Select only baselines between the antennas specified by the selector ANT1.
  • ’ANT1&ANT2’ — Select only the cross-correlation baselines between the antennas specified by

selector ANT1 and antennas specified by selector ANT2. Thus ’ANT1&’ is an abbreviation for ’ANT1&ANT1’.

  • ’ANT1&&ANT2’ — Select only auto-correlation and cross-correlation baselines between antennas

specified by the selectors ANT1 and ANT2. Note that this is what the default antenna=’’ gives you.

  • ’ANT1&&&’ — Select only autocorrelations specified by the selector ANT1.
