Basic Information on mosgen
Purpose: Generate a mosaic file for the on-line system or for UVGEN.
Categories: uv analysis
MOSGEN generates a file containing mosaic pointing centres. The
output format may be chosen either for the ATCA on-line system
RA and DEC of the centre of the mosaic in hh:mm:ss,dd:mm:ss
format, or decimal hours and degrees. The default is 0,0.
Width of the field to mosaic, in degrees. One or two values can
be given, being the width in RA and DEC. Default is 0.1 deg.
The observing frequency, in GHz. Default is 1.4 GHz.
Standard PGPLOT plotting device to display a diagram of the
pointing centres relative to the mosaic centre. Default is not
to produce a plot.
Output file listing the pointing centres. Default is the
Output file listing the pointing centres in a form suitable for
display with the task cgdisp. If unset, no overlay is output.
Format of the output file:
atmosaic Mosaic file format understood by the ATCA on-line
NOTE: The ATCA mosaic files produced by mosgen have
the offsets referenced to the pointing in the lower
left corner (earliest RA, least DEC value). That
is, it is not the centre of the mosaic given by the
user. The coordinate of the reference pointing is
given as a comment in the head of the file. The
reason for the use of the lower left is to minimise
drive times and to pixel the reference as the first
point in the mosaic that rises. Note the ATCA on-
line system has a limit of 2048 pointing centers.
uvgen Format required for UVGEN's "center" keyword.
Primary beam type. Default is ATCA.
For mode=atmosaic, a name used to derive the pointing name. For
example, using name=lmc, MOSGEN will generate pointing names of
lmc_1, lmc_2, etc. The full name must be 9 characters or less.
For mode=atmosaic, the number of cycles spent on each pointing.
