DESCRIPTION

MFPLAN helps determine observing frequencies for multi-frequency synthesis experiments with the ATCA.  

PARAMETERS

freq
Frequency bands (in GHz) to search for good mfs setups. This consists of a number of pairs of frequencies, giving the lower and upper limits on bands appropriate for observing. Several bands will often be given to avoid frequencies which suffer from interference or birdies. The nominal frequency bands of the AT receivers are:
  1.35,1.78    (L band)
  2.20,2.50    (S band)
  4.544,6.336  (C band)
  8.00,9.20    (X band)
The default is 4.544,6.336.
nfreq
Number of frequencies per configuration. Generally 2 or 4 are the most usual numbers for the ATCA. Default is 2.
nants
Number of antennae to use. Sensible values are either 5 or 6. Default is 6.
config
Array configuration. Several values can be given. Valid values are: 3.0a (6.0a), 3.0b (6.0b), 3.0c (6.0c), 3.0d (6.0d), 1.5a, 1.5b, 1.5c, 1.5d, 0.75a, 0.75b, 0.75c, 0.75d, 0.375, 0.122. These correspond to the 14 standard ATCA configurations.
fixed
List of fixed frequencies that are fixed (not varied) by MFPLAN. Usually these correspond to frequencies used in completed observations. The first "nfreq" frequencies will be associated with the first configuration, the second "nfreq" frequencies correspond to the second configuration, etc. The default is that all frequencies are varied.
options
Extra processing options. Several can be given, separated by commas. Minimum match is used. Possible values are:
  no128    Frequencies that are multiples of 128 MHz are to be
           avoided. All resulting frequencies are odd multiples
           of 64 MHz.
  infinity Minimise the worst gap in the uv coverage. The default
           is to minimise the rms gap in the uv coverage. The
           infinity option is the best option if you have very good
           uv coverage. Otherwise it produces poorer results.
  colours  Plot each configuration with a different colour
device
PGPLOT device. If this is given, then a plot of the u-v coverage is made. Default is no plot.
