### MAPTOL

Specifies when to stop iterating

#### Description:

If the normalised change (either the mean or maximum change - see parameter "maptol_mean" ) between the maps created on subsequent iterations falls below the value of maptol, then the map-maker performs one more iteration and then terminates. Only used if parameter "numiter" is negative. The normalised mean (or maximum) change between maps is defined as the mean (or maximum) of the absolute change in map pixel value, taken over all pixels within the region of the AST mask (if any, see parameter "ast.zero_mask" , etc), and normalised by the RMS of the square root of the pixel variances. Compared to parameter "chitol" , this is much more like a " by eye" test, that will stop the solution when the map stops changing. [0.05]
