DESCRIPTION

SINPOLY - Fit polynomial baselines to autocorrelation data. Polynomial fits for each antenna and polarization are subtracted from the output averaged data.  

PARAMETERS

vis
The name of the input uv-data file.
select
The normal uv selection commands. The default is use everything. See the help on "select" for more details.
line
The normal uv linetype in the form:
  line,nchan,start,width,step
See the help on "line" for more details. The default is all channels. The output will consist of only spectral data.
interval
Time averaging interval, in minutes. The default is 0. (i.e. no averaging).
out
The name of the output uv data set. No default.
options
This gives extra processing options. Several options can be given, each separated by commas. They may be abbreviated to the minimum needed to avoid ambiguity. Possible options are:
   'nocal'      Do not apply the gains file. By default, SINPOLY
                applies the gains file in copying the data.
   'nopol'      Do not apply polarization corrections. By default
                SINPOLY corrects for polarization cross-talk.
   'window'     Fit polynomial to each spectral window.
                Default is to fit all channels.
   'dsb'        Fit polynomial to each sideband for double sideband
                spectra. 'dsb' and 'window' are mutually exclusive.
device
PGPLOT device for polynomial fits. The default is to ask user.
nxy
Two values. Number of plot windows in x and y, Default nx=1, ny=nx.
npoly
The order of the Lagrange polynomial fit to the averaged uv-data. Different values can be given for each window. The maximum is 8th order polynomial. Default 0,0,0,0,0,0,0,0,0,0,0,0
badchan
Number of ranges of bad channels followed by list of up to 20 pairs of numbers to specify range of channels to exclude in polyfit. e.g. to exclude 2 center channels in eight 64-channel windows, use: badchan=8,32,33,96,97,160,161,224,225,288,289,352,353,416,417,480,481
endchan
Number of channels to drop from window edges in polyfit. Default=4.
