Public: Peel strong source from UV data based on previous CLEAN.
Picks the strongest field with peak above PeelFlux and subtracts all others using the SkyModel on myClean and then self calibrates the residual data to obtain a best model and calibration for that field. This model is then subtracted using the derived calibration and then the calibration is undone. The imaging is then redone using the myClean setup and the components removed from the Peeled field are appended to the end of the CC Table 1 corresponding field on the mosaic on myClean. The components peeled are written to CC Table 2 on the output Peeled image. Note: If multiple peels are done, the components from previously peeled fields will not be in Table 1 and the components from CC table 2 need to be copied to table 1 No restoration or flattening is done. - Parameters:
-

| inUV | Data to be peeled, on return all SN tables will be removed. and peeled source will have been subtracted |
| myClean | Clean object which has previously been CLEANed and which has a field with a CC peak in excess of PeelFlux. Need for peeling based on values of myClean->peakFlux and PeelFlux. The test for individual fields is the maximum as determined from the CLEAN components by ObitImageMosaicMaxField On output, this will include info on last CLEAN |
| err | Error/message stack |
- Returns:
- the 1-rel field number of the peeled field or -1 if no peel
