The supplied value should be either a comma-separated list of strings or the name of a text file preceded by an up-arrow character "", containing one or more comma-separated lists of strings. Each string is either a "keyword=value" setting, or the name of a text file preceded by an up-arrow character "". Such text files should contain further comma-separated lists which will be read and interpreted in the same manner (any blank lines or lines beginning with "#" are ignored). Within a text file, newlines can be used as delimiters, as well as commas. Settings are applied in the order in which they occur within the list, with later settings over-riding any earlier settings given for the same keyword.
Each individual setting should be of the form:
The available parameters are identical to the cleaning parameters used by the iterative map-maker (method=ITER) and the available parameters are listed in the "Configuration Parameters" appendix of SUN/258. Default values will be used for any unspecified parameters. Assigning the value "def" (case insensitive) to a keyword has the effect of resetting it to its default value. Options available to the map-maker but not understood by SC2CLEAN will be ignored. Parameters not understood will trigger an error. Use the "cleandk." namespace for configuring cleaning parameters for the dark squids. [current value]
