Clean beam user specification
BEAM_SIZE [ 0 0 0 ] Major, Minor (in arcsec) and PA (in Degree)
Method dependent CLEAN parameters
CLEAN_INFLATE [ ] Maximum Inflation factor for UV_RESTORE (MULTISCALE) CLEAN_NCYCLE [ ] Max number of Major Cycles (SDI & CLARK methods) CLEAN_NGOAL [ ] Max number of comp. in Cycles (ALMA method) CLEAN_RATIO [ ] Smoothing factor (MRC default 0: guess, otherwise must be 2^n) CLEAN_SIDELOBE [ ] Min threshold to fit the synthesized beam CLEAN_SMOOTH [ ] Smoothing ratio: MRC (def 2 or 4) and MULTISCALE (def sqrt(3)) CLEAN_SPEEDY [ ] Speed-up factor (CLARK) CLEAN_WORRY [ ] Worry factor (CLARK and MULTISCALE)
Mosaic related parameters
MOSAIC_SEARCH [ ] Threshold to search Clean Comp. in a Mosaic (def 0.2) MOSAIC_TRUNCATE [ ] Threshold to mask outer regions in a Mosaic (def 0.2)
Old (seldom used) names like in MAPPING
BLC [ pixel] Bottom left corner of cleaning box TRC [ pixel] Top right corner of cleaning box BEAM_PATCH [ pixel] Size of cleaning beam ** not clear **
Restoration control CLEAN parameters
CLEAN_RESIDUAL [-1,0,1] Control how residuals are added or not - For debug mostly.
