analysis.  

DESCRIPTION

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.  

PARAMETERS

inq
Cube containing dirty Q spectra. No default.
inu
Cube containing dirty U spectra. No default.
freq
Ascii file containing the observed frequencies. No default. The file should contain one frequency per line, in Hertz. Comment lines aren't allowed.
nmax
Maximum number of iterations per pixel. Default 1000.
gain
CLEAN loop gain. Default 0.1.
cutoff
CLEAN cutoff (in P, without bias correction). Default 0.
fwhm
FWHM of restoring RM beam, in rad/m^2. Default 0==auto.
method
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.
outq
Output (CLEANed) Q cube. Default 'Qclean'.
outu
Output (CLEANed) U cube. Default 'Uclean'.
modq
Model (CLEANed) Q cube. Default 'Qmodel'.
modu
Model (CLEANed) U cube. Default 'Umodel'.
resq
Residual Q cube. Default 'Qresid'.
resu
Residual U cube. Default 'Uresid'.
ni
Number of CLEAN iterations per pixel. Default 'niters'.
debug
Debug mode? 0=no, 1=yes. Default 0.
