FIND /SWITCHING

            LAS\FIND /SWITCHING Mode

        Select observations according to their switching mode:
          - *: any defined or unknown switch
          - POSITION: position switch
          - FREQUENCY: unfolded frequency switch
          - FOLDED: folded frequency switch
          - WOBBLER: wobbler switch
          - BEAM: beam switch
          - MIXED: special code for mixed modes e.g. after averaging spectra
          - UNKNOWN: if the switching information is missing or no switching
              performed (e.g. CALSKY).

        Note that evaluating the switching mode is unefficient since this infor-
        mation is not saved in the CLASS index, and requires to read each obser-
        vation  header  one  by one. Identifying observations by e.g. their date
        and scan number is more efficient, either by proper bookkeeping  at  the
        telescope, or with a once-for-all use of the /SWITCHING option.
