If itermap is set to a positive value, the map from each iteration of each chunk will be stored in an output NDF. If itermap is set to a negative value, only the final iteration will be written from each chunk. If its absolute value is larger than 1, then each itermap will include a quality component that reflects the AST mask in use.

By default, each itermap NDF will be stored in an extension called .MORE.SMURF.ITERMAPS in the main output NDF. However, an alternative location can be specified by supplying a value for ADAM parameter ITERMAPS. This is useful as it allows you to look at earlier itermaps whilst makemap is still running. [0]
