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 USE IN command.
/SPECIES refine the search to lines of one or more species. The
species name should match exactly that in the database.
Wildcards '*' are accepted. Default is "All".
/ENERGY refine the search to lines with upper level energy lower
than ENERGY, expressed in Kelvins.
/AIJ refine the search to lines with Einstein A coefficient
greater than AMIN, expressed in s-1.
/DELTA search for lines within DFREQ, expressed in MHz, from the
cursor position. Default is 10 times the channel width.
/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).
/LOOP by default, the cursor is invoked only once, but you can
iterate indefinitely with the option /LOOP. Type 'E' to
exit the loop.
/COLOR customize the color of the line and its label. See PEN
/COLOUR ? or Menu > Demos > Greg > PENCIL color names for
possible colors. By default, the lines are plotted in red
for signal band and blue for image band.
/ANGLE customize the angle of the label (degrees). Default is 90.
