Null Value: NONE ( 0 => no gain error) Tasks: CALIB.....Determines antenna calibration: complex gain. GAINERR is used only with the gain contrained solution type. SCIMG.....Full-featured imaging plus self-calibration loop with editing. GAINERR as in CALIB durinng self-cal steps. SCMAP.....Imaging plus self-calibration loop with editing. GAINERR as in CALIB durinng self-cal steps. UVFIT.....Fits source models to uv data. GAINERR are the initial guesses of the antenna gains to be fit. 0 -> no fit. UVGIT.....Fits source models to uv data. GAINERR are the initial guesses of the antenna gains to be fit. 0 -> no fit. Procedures: IMSCAL....Large image self-cal with IM2CC and OOCAL. GAINERR is passed to CALIB. OOCAL.....Determines antenna complex gain with frequency-dependent models. GAINERR is passed to CALIB. ----------------------------------------------------------------
