rmclean - Run RM-CLEAN on a set of 'dirty' rm-cubes
RMCLEAN reads in dirty Q and U cubes, generates rmtf based on
the frequencies given in an ascii file, and cleans the rm
spectra following the algorithm given by Brentjens (2007).
The output cubes contain the clean model components and the
CLEANed rm spectra.
The input cubes must be reordered with mode=312, and the
output cubes will have the same ordering and thus must be
reordered after being written to disk. A script (runrmclean.py)
is provided to put everything together into one step.
Cube containing dirty Q spectra. No default.
Cube containing dirty U spectra. No default.
Ascii file containing the observed frequencies. No default.
The file should contain one frequency per line, in Hertz.
Comment lines aren't allowed.
Maximum number of iterations per pixel. Default 1000.
CLEAN loop gain. Default 0.1.
CLEAN cutoff (in P, without bias correction). Default 0.
FWHM of restoring RM beam, in rad/m^2. Default 0==auto.
Method for determining clean component locations. Choices are:
the P spectrum at each iteration, and find the
location of the largest value in the amplitude
of the cross-correlation spectrum.
The cross-correlation option is slower, but should be better,
especially in low signal-to-noise situations, and is default.
Output (CLEANed) Q cube. Default 'Qclean'.
Output (CLEANed) U cube. Default 'Uclean'.
Model (CLEANed) Q cube. Default 'Qmodel'.
Model (CLEANed) U cube. Default 'Umodel'.
Residual Q cube. Default 'Qresid'.
Residual U cube. Default 'Uresid'.
Number of CLEAN iterations per pixel. Default 'niters'.
Debug mode? 0=no, 1=yes. Default 0.
