[WEEDS\]LFIND [SPECIES [FMIN FMAX]] [/SORTBY ORDER] [/ENERGY ENERGY]
Find the lines within a frequency range and create a line index. The
command looks for the lines between FMIN and FMAX in the database se-
lected with the USE IN command. If not specified, the values of FMIN and
FMAX are taken from the current spectra.
SPECIES the name of the species. Default is "All".
FMIN the minimum frequency in MHz.
FMAX the maximum frequency in MHz
/SORTBY sort the lines according to ORDER, which can be any combi-
nation of "frequency", "energy" and "aeinstein", and all
the subsequent permutations.
/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 s-1.
