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 ob-
tained 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.
