    Search for lines in the database around a  central  frequency  and  mark
    them  on  the  current spectra. By default, the central frequency is se-
    lected with the mouse left button. The search is done in an interval  of
    width  DFREQ around the selected frequency; alternatively, the /FULL op-
    tion may be used to search for lines over  the  entire  frequency  range
    covered by the current spectra. The line database in which the search is
    performed may be selected with the DBSELECT command.

    Options:
      /SPECIES    refine the search to lines of a given species. The species
                  name should match exactly that in the database. Default is
                  "All".

      /ENERGY     refine the search to lines with upper level  energy  lower
                  than ENERGY, expressed in Kelvins.

      /AEINSTEIN  refine  the  search  to  lines with einstein A coefficient
                  greater than AEINSTEIN, expressed in Kelvins.

      /DELTA      search for lines within DFREQ, expressed in MHz, from  the
                  cursor position. Default is 1 MHz.

      /FULL       search  for  lines  in the full frequency range covered by
                  the current spectra.

      /IMAGE      search for lines in the image sideband. Note that this  is
                  the default if the spectra lower axis unit is I (image).
