Basic Information on fakeotf
Purpose: Generate a fake RPFITS file from an existing one
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.
Input RPFITS file, which should be an OTF map. It is assumed
that the position and spectral timestamps match; if not run
Output RPFITS file. No default.
Amplitude and sigma of spectral Gaussian, in K and channel
units. Default is 1,20 - i.e. 1 K and 20 channels.
RA,DEC of centre position for image Gaussian. No default, but
can be omitted if fwhm=0.
FWHM of image Gaussian in arcsec (default 30). Give 0 for flat
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.
