Description
Perform a test. The dataset used is an observation of 3C273 at 8GHz
using the C-configuration of the VLA. It is part of the
AIPS++ distribution.
Note that if doshift is set to T then the imaging is done in
Galactic coordinates.
The test does the following:
- The uvfits file that is to be read in is
in a standard place in the AIPS++ code source area.
- The MeasurementSet is read from the uvfits file.
- A summary of what exists is logged.
- The data are weighted using the Briggs algorithm.
- An initial CLEAN-only deconvolution is performed, and then restored.
- A CLEAN mask is constructed by thresholding I > 0.015
- The deconvolution is repeated with
masks enabled.
- Residual images are calculated for the North Celestial pole,
on the Sun, and for azimuth elevation (0d, 0d).
