PARAMETERS

vis
Name of input visibility data file. No default.
again
`again' gives an antenna amplitude factor as a function
         again * sqrt(total_power/systemp)
Default value 0. gives no amplitude change.
rgain
`rgain' gives an antenna amplitude factor as a function
         rgain * sqrt(systemp/total_power)
Default value 0. gives no amplitude change.
pgain
`pgain' gives the antenna phase change with total power in degrees/Kelvin. Default value is 0. i.e. No phase change. Typical value at 100 GHz is pgain = -280 degrees/K.
scale
Scale total power to tsys [K]. Default no scaling applied. Three values for each antenna: tpower = a + b*tpower + c*tpower**2 These values can be obtained by editing the log file from VARFIT E.g. varfit vis=? xaxis=tpower refant=1 options=xscale log=varlog The quadratic term is currently ignored.
refant
Compute the antenna gains relative to refant. The gain of refant is set to cmplx(1.,0.). Default=0. no refant.
out
Name of output calibration file. The default is to write the gain corrections into the input visibility file.
