2.3.4.2 The scan Parameter

The scan parameter selects the scan ID numbers of the data. There is currently no naming convention for scans. The scan ID is filled into the MS depending on how the data was obtained, so use this with care.

Examples:

  scan = ’3’                      # scan number 3.
  scan = ’1~8’                    # scan numbers 1 through 8, inclusive
  scan = ’1,2,4,6’                # scans 1,2,4,6
  scan = ’<9’                     # scans <9 (1-8)

NOTE: ALMA and VLA/JVLA number scans starting with 1 and not 0. You can see what the numbering is in your MS using the listobs task with verbose=True (see § 2.2.6).
