Construct filtered field from optimal filter and data sky.

Usage: s2fil_field_construct

[-help]: Display usage information.
[-filter filename_filter]: Name of optimal filter to read and to be used to filter the data sky map. Note that filter file header also contains names of associated child files that also contain filter data to be read.
[-data filename_sky]: Name of data sky fits file to read sky data from.
[-filetype sky_file_type_str]: String specifying type of data sky fits file, either 'map' or 'sky'.
[-field filename_field]: Name of field file to write. Note field data is also written to assocaited child files, the names of which are stored in the field file header.
[-ngamma n_gamma]: Number of orientations to consider when filtering.
[-write_filter write_filter]: Logical to specify whether to write an optimal filter file as an associated child file of the s2fil field. This may not be necessary since the optimal filter will most likely be read from a file of this type and so to avoid duplication another need not be written.
