16 listcal ---- List antenna gain solutions
20 This task lists antenna gain solutions in tabular form. The table
21 is organized as follows. Solutions are output by
22 1) Spectral window,
23 2) Antenna,
24 3) Time,
25 4) Channel,
26 5) and Polarization;
27 where the inner-most loop is over polarization.
29 The listcal output table contains two table headers. The top-level header
30 is printed each time the spectral window changes. This header lists
31 the spectral window ID (SpwID), the date of observation (Date),
32 the calibration table name (CalTable), and the measurement set name (MS name).
34 A lower-level header is printed when the the top-level header is printed,
35 when the antenna names change, and every `pagerows' of output.
36 The lower-level header columns are described here:
38 Column Name Description
39 ----------- -----------
40 Ant Antenna name (contains sub-columns: Amp, Phs, F)
41 Time Visibility timestamp corresponding to gain solution
42 Field Field name
43 Chn Channel number
44 Amp Complex solution amplitude
45 Phs Complex solution phase
46 F Flag
48 Elements of the ``F'' column contain an `F' when the datum is flagged,
49 and ` ' (whitespace) when the datum is not flagged.
51 Presently, the polarization mode names (for example: R, L)
52 are not given, but the ordering of the polrization modes (left-to-right) is
53 equivalent to the order output by task listobs (see ``Feeds'' in listobs
54 output).

74 spw Select spectral window, channel to list
75 default: '' --> All spws and channels;
76 spw='2:34' spectral window 2, channel 34
