NAME

wvcal - Estimate antenna gains from WVR measurements.  

PERSON RESPONSIBLE

CATEGORIES

calibration, atmospheric phase  

DESCRIPTION

WVCAL estimates atmospheric phase corrections from WVR measurements. The WVR data are interpolated to the integration times of the interferometer data and written into the gains item.  

PARAMETERS

vis
Name of input uv-data file. No default.
wvr
Name of input WVR data files. WVCAL looks for filenames wvrN, where N=1,nants. The phase correction is set to zero if no WVR data file is found for any antenna. No default.
pgain
`pgain' gives the antenna phase change with WVR path length in in units of radians/millimeter. Default = 0. calculates -2pi/lambda radians/millimeter from the observing frequency.
interval
The length of time, in minutes, of a gain solution. Default uses the interferometer integration interval, but use a larger value in cases of poor signal to noise, or if the atmosphere and instrument is fairly stable.
timeoff
time offset in seconds for each antenna.
out
Name of output uv-data file. The default is to write the gain corrections into the input visibility file.
device
PGPLOT device to plot mmpath versus airmass. Default is no plot.
airmass
airmass range (min,max) to use. default=1,5
mmpath
mmpath range (min,max) to use. default=0,1000.
options
Extra processing options. Several can be given, separated by commas. Minimum match is used. Possible values are:
  filter   Filter out data more than 2 sigma from the mean path.
  scale    Scale the measured path by the slope for each antenna.
  subtract Subtract the average for each antenna.
