AST.ZERO_NITER

Allows AST masking to be switched off after a given number of iterations

Description:

If ast.zero_niter is non-zero, it gives the number of iterations for which the AST model should be masked. Subsequent iterations are not masked. A value of zero means " mask on all iterations" . However, if parameter "ast.zero_notlast" is set, the mask will will not be applied on the last iteration, even if ast.zero_niter is zero. This feature will probably be useful for deep point-source observations for which the large-scale noise is not as important, but keeping as much data around the edges of the map is. Note, any initial iterations specified by parameter "ast.skip" are not included in the count of iterations. [0]
