5.3.4.2 Sub-parameter cyclespeedup

This sub-parameter is activated for imagermode=’csclean’ and ’mosaic’.

The cyclespeedup parameter allows the user to let clean to raise the threshold at which a major cycle is forced if it is not converging to that threshold. To do this, set cyclespeedup to an integer number of iterations at which if the threshold is not reached, the threshold will be doubled. See cyclefactor above for more details. By default this is turned off (cyclespeedup = -1). In our tests, a value like cyclespeedup = 50 has been used successfully.
