21.4.29      SELF_NITER

Variable length array specifying the number of Clean components retained for each loop of the self-calibration process. Default is 0, meaning all Clean components found by CLEAN.

For simple structures and Phase calibration, 10 may be enough. For more complex ones, be sure to include enough Clean components in the model. More components can be taken at each step, although the better knowledge of phase errors often allows the source to be represented with a smaller number of components after self-calibration than before. The default is a reasonably good compromise, although faster convergence may be obtained with smaller number of components.

This variable length array can be resized using the LET /RESIZE command. For example

     LET SELF_NITER 10 0 0 /RESIZE

will lead to 3 self-calibration loops (if SELF_TIMES and SELF_MINFLUX are also of size 3), the first one selecting only 10 components, the two others all components.
