Solve for pointing error calibration:

This program is under development.  Please do not use.

Keyword arguments:
vis -- Name of input visibility file (MS)
        default: <unset>; example: vis='ngc5921.ms'
model -- Name of input model (component list or image)
        default: <unset>; example: model='ngc5921.im'
caltable -- Name of output Pointing calibration table
        default: <unset>; example: caltable='ngc5921.gcal'

--- Data Selection (see help par.selectdata for more detailed information)

       field -- Select field using field id(s) or field name(s).
          [run listobs to obtain the list id's or names]
       default: ''=all fields
       If field string is a non-negative integer, it is assumed a field index
         otherwise, it is assumed a field name
       field='0~2'; field ids 0,1,2
       field='0,4,5~7'; field ids 0,4,5,6,7
       field='3C286,3C295'; field named 3C286 adn 3C295
       field = '3,4C*'; field id 3, all names starting with 4C
       spw -- Select spectral window/channels
       default: ''=all spectral windows and channels
       spw='0~2,4'; spectral windows 0,1,2,4 (all channels)
       spw='<2';  spectral windows less than 2 (i.e. 0,1)
       spw='0:5~61'; spw 0, channels 5 to 61
       spw='0,10,3:3~45'; spw 0,10 all channels, spw 3, channels 3 to 45.
       spw='0~2:2~6'; spw 0,1,2 with channels 2 through 6 in each.
       spw='0:0~10;15~60'; spectral window 0 with channels 0-10,15-60
       spw='0:0~10,1:20~30,2:1;2;3'; spw 0, channels 0-10,
                spw 1, channels 20-30, and spw 2, channels, 1,2 and 3

       selectdata -- Other data selection parameters
       default: True
       timerange  -- Select data based on time range:
       default = '' (all); examples,
       timerange = 'YYYY/MM/DD/hh:mm:ss~YYYY/MM/DD/hh:mm:ss'
       Note: if YYYY/MM/DD is missing dat defaults to first day in data set
       timerange='09:14:0~09:54:0' picks 40 min on first day
       timerange= '25:00:00~27:30:00' picks 1 hr to 3 hr 30min on next day
       timerange='09:44:00' data within one integration of time
       timerange='>10:24:00' data after this time
       uvrange -- Select data within uvrange (default units kilo-lambda)
       default: '' (all); example:
       uvrange='0~1000'; uvrange from 0-1000 kilo-lamgda
       uvrange='>4';uvranges greater than 4 kilo lambda
       antenna -- Select data based on antenna/baseline
       default: '' (all)
       If antenna string is a non-negative integer, it is assumed an antenna index
         otherwise, it is assumed as an antenna name
       antenna='5&6'; baseline between antenna index 5 and index 6.
       antenna='VA05&VA06'; baseline between VLA antenna 5 and 6.
       antenna='5&6;7&8'; baseline 5-6 and 7-8
       antenna='5'; all baselines with antenna 5
       antenna='5,6,10'; all baselines with antennas 5 and 6
       scan -- Scan number range - New, under developement
       msselect -- Optional complex data selection (ignore for now)

gaincurve -- Apply VLA antenna gain curve correction (True/False)
        default: False; 
        Use gaincurve=True ONLY for VLA data
opacity -- Opacity correction to apply
        default: 0.0 (no opacity correction)
        example: opacity=0.051
solint --  Solution interval (sec)
        default: 0.0 (scan based); example: solint=60.
