Select lines available from the input database. An index containing the
line information is formed and a SIC structure mapping these information
is defined. The index can be sorted by increasing frequency or energy.
One or more species name can be provided, wildcards '*' can be used.
The initial origin of the line (e.g. JPL, CDMS or private catalog), the
name of the species, a frequency range, the maximum energy of the upper
level and the maximum Einstein coefficient Amax can be used as filters
in the line selection process.
As an output, the LINES SIC structure will contain the content of the
current index, i.e.,
LINES% Global structure
LINES%N Integer scalar [---] Number of lines in current inde
LINES%SPECIES Character[LINES%N] [---] Species names
LINES%FREQUENCY Double[LINES%N] [MHz] Frequencies
LINES%UNCERTAINTY Real[LINES%N] [MHz] Uncertainty of the line frequen
LINES%AIJ Double[LINES%N] [s-1] Einstein coefficient
LINES%EUP Real[LINES%N] [ K] Upper level energy
LINES%GUP Real[LINES%N] [---] Upper level degeneracy
LINES%QNUP Character[LINES%N] [---] Upper level quantum numbers
LINES%ELOW Real[LINES%N] [ K] Lower level energy
LINES%GLOW Real[LINES%N] [---] Lower level degeneracy
LINES%QNLOW Character[LINES%N] [---] Lower level quantum numbers
The lines will be sorted according to Order, which can be any combina-
tion of "frequency", "energy" and "aij", and all the subsequent permuta-
tions. Default is frequency. If sortby is ["energy", "aij"] and if ep-
silon is specified, aij will be used as a criterion when the difference
in energy is less than epsilon.
