DESCRIPTION

MOSPSF is a MIRIAD task which determines the point spread function for a linear mosaic of dirty images (as produced by INVERT).

Strictly speaking, the PSF varies with position and frequency. However if the pointing grid is fairly complete and the individual synthesised beam patterns are similar, the PSF is reasonably independent of position. It is also usually a good approximation that it is independent of frequency.  

PARAMETERS

beam
This gives the name of the input beam-cube (as produced by INVERT). No default.
out
The name of the output point-spread function. It will be the same size as the input.
radec
The RA and DEC (either in the form hh:mm:ss,dd:mm:ss or decimals hours and degrees) at which to compute the point-spread function. The default is the reference RA,DEC of the beam-cube.
freq
The frequency (in GHz) at which to compute the point-spread function. The default is the reference frequency of the beam-cube. The point-spread function is reasonably independent of frequency for most spectral line observations.
