DESCRIPTION

FAKEOTF reads an RPFITS file and replaces all spectra with a single Gaussian profile. The amplitude of the Gaussian is either constant across the map (fwhm=0) or falls of as a circular 2-D Gaussian in the image plane. A new RPFITS file is produced. Use this to simulate the effects of Gridzilla on Mopra OTF data. Limitation: The same parameters will be used for all IFs.  

PARAMETERS

in
Input RPFITS file, which should be an OTF map. It is assumed that the position and spectral timestamps match; if not run MOPFIX first.
out
Output RPFITS file. No default.
specpar
Amplitude and sigma of spectral Gaussian, in K and channel units. Default is 1,20 - i.e. 1 K and 20 channels.
centre
RA,DEC of centre position for image Gaussian. No default, but can be omitted if fwhm=0.
fwhm
FWHM of image Gaussian in arcsec (default 30). Give 0 for flat plane.
tsys
System temps for channels A and B respectively. If only one value is given, this is used for both channels. This is also used to determine the amount of noise in each spectrum. Default is to use the original Tsys measurements from the input file.
