16 fields

(1) The R, I, C symbols are abbreviations for the conventional Real, Integer and Character Fortran type declarators.
(2) The F, D, I, C symbols are abbreviations for the standard float, double, integer and char C type declarators.
(3) Real type values (Fortran R* or C F, D) are stored in  IEEE format,
  Character strings (E and J fields) are blank right justified (no ending null character).
(4) The A-J fields are those used in the GEISA software:
   (A)  Wavenumber (cm-1) of the line associated with the vibro-rotational transition.
   (B)  Intensity of the line (cm molecule-1 at 296K).
   (C)  Lorentzian collision halfwidth (cm-1 atm-1 at 296K).
   (D)  Energy of the lower transition level (cm-1).
   (E)  Transition quantum identifications for the lower and upper levels of the transition, as the following:
        TRS1  upper state vibrational identification,
        TRS2  lower state vibrational identification,
        RN1   upper state rotational identification,
        RN2   lower state rotational identification.
        Blank fields (spaces) at this place match missing information.
   (F)  Temperature dependence coefficient n of the halfwidth. Its value is set to zero if n is not available.
   (G)  Identification code for isotope.
   (I)   Identification code for molecule.
   (J)   Internal GEISA code for data identification.
(5)The K-Q fields correspond to information related to the actual transition, in a purpose of possible intercomparaison with the HITRAN database.
   These fields, not of prime importance for the GEISA software, contain the following parameters:
   (K)  Molecule number.
   (L)  Isotope number (1=most abundant, 2=second, etc.).
   (M)  Transition probability (debye).
   (N)  Self-broadened halfwidth (HWHM) (cm-1 atm-1 at 296K).
   (O)  Air-broadened pressure shift of line transition (cm-1 atm-1).
   (P)  Accuracy indices for frequency, intensity and halfwidth.
   (Q)  Indices for lookup of references for frequency, intensity and halfwidth.
