        sdfile -- name of input SD dataset
        scanlist -- list of to process
                default: [] (use all scans)

                         this selection is in addition to field,

        field -- selection string for selecting scans by name
                default: ’’ (no name selection)
                example: ’FLS3a*’
                         this selection is in addition to scanlist,
                         iflist, and pollist
        iflist -- list of IF id numbers to select
                default: [] (use all IFs)
                example: [15]
                         this selection is in addition to scanlist,
                         field, and pollist
        pollist -- list of polarization id numbers to select
                default: [] (use all polarizations)

        DESCRIPTION:

        Task sdsave writes the single dish data to a disk file in
        specified format (ASAP, MS2, SDFITS, ASCII). It is possible to
        save the subset of the data by selecting scan numbers, IF ids,
        polarization ids and field names. The ASAP (scantable) format
        is recommended for further analysis using Sd tool. For further
        imaging using imager, save the data to the Measurement Set (MS2).
