Read from JPL.
The JPL format is as follows (directly taken from the JPL documentation):
The catalog line files are composed of 80-character lines, with one line entry per spectral line. The format of each line is: \label{lfmt} \begin{tabular}{@{}lccccccccr@{}} FREQ, & ERR, & LGINT, & DR, & ELO, & GUP, & TAG, & QNFMT, & QN${'}$, & QN${''}$\\ (F13.4, & F8.4, & F8.4, & I2, & F10.4, & I3, & I7, & I4, & 6I2, & 6I2)\\ \end{tabular} \begin{tabular}{lp{4.5in}} FREQ: & Frequency of the line in MHz.\\ ERR: & Estimated or experimental error of FREQ in MHz.\\ LGINT: &Base 10 logarithm of the integrated intensity in units of \linebreak nm$^2$$\cdot$MHz at 300 K. (See Section 3 for conversions to other units.)\\ DR: & Degrees of freedom in the rotational partition function (0 for atoms, 2 for linear molecules, and 3 for nonlinear molecules).\\ ELO: &Lower state energy in cm$^{-1}$ relative to the lowest energy spin--rotation level in ground vibronic state.\\ GUP: & Upper state degeneracy.\\ TAG: & Species tag or molecular identifier. A negative value flags that the line frequency has been measured in the laboratory. The absolute value of TAG is then the species tag and ERR is the reported experimental error. The three most significant digits of the species tag are coded as the mass number of the species, as explained above.\\ QNFMT: &Identifies the format of the quantum numbers given in the field QN. These quantum number formats are given in Section 5 and are different from those in the first two editions of the catalog.\\ QN${'}$: & Quantum numbers for the upper state coded according to QNFMT.\\ QN${''}$: & Quantum numbers for the lower state.\\ \end{tabular} *

Absorption::SingleLineExternal Absorption::ReadFromLBLRTMStream | ( | istream & | is | ) |
Read from LBLRTM.
LBLRTM follows the old HITRAN format from before 2004. This HITRAN format is as follows (directly from the HITRAN documentation):
Each line consists of 100 bytes of ASCII text data, followed by a line feed (ASCII 10) and carriage return (ASCII 13) character, for a total of 102 bytes per line. Each line can be read using the following READ and FORMAT statement pair (for a FORTRAN sequential access read): READ(3,800) MO,ISO,V,S,R,AGAM,SGAM,E,N,d,V1,V2,Q1,Q2,IERF,IERS, * IERH,IREFF,IREFS,IREFH 800 FORMAT(I2,I1,F12.6,1P2E10.3,0P2F5.4,F10.4,F4.2,F8.6,2I3,2A9,3I1,3I2) Each item is defined below, with its format shown in parenthesis. MO (I2) = molecule number ISO (I1) = isotopologue number (1 = most abundant, 2 = second, etc) V (F12.6) = frequency of transition in wavenumbers (cm-1) S (E10.3) = intensity in cm-1/(molec * cm-2) at 296 Kelvin R (E10.3) = transition probability squared in Debyes**2 AGAM (F5.4) = air-broadened halfwidth (HWHM) in cm-1/atm at 296 Kelvin SGAM (F5.4) = self-broadened halfwidth (HWHM) in cm-1/atm at 296 Kelvin E (F10.4) = lower state energy in wavenumbers (cm-1) N (F4.2) = coefficient of temperature dependence of air-broadened halfwidth d (F8.6) = shift of transition due to pressure (cm-1) V1 (I3) = upper state global quanta index V2 (I3) = lower state global quanta index Q1 (A9) = upper state local quanta Q2 (A9) = lower state local quanta IERF (I1) = accuracy index for frequency reference IERS (I1) = accuracy index for intensity reference IERH (I1) = accuracy index for halfwidth reference IREFF (I2) = lookup index for frequency IREFS (I2) = lookup index for intensity IREFH (I2) = lookup index for halfwidth The molecule numbers are encoded as shown in the table below: 0= Null 1= H2O 2= CO2 3= O3 4= N2O 5= CO 6= CH4 7= O2 8= NO 9= SO2 10= NO2 11= NH3 12= HNO3 13= OH 14= HF 15= HCl 16= HBr 17= HI 18= ClO 19= OCS 20= H2CO 21= HOCl 22= N2 23= HCN 24=CH3Cl 25= H2O2 26= C2H2 27= C2H6 28= PH3 29= COF2 30= SF6 31= H2S 32=HCOOH *
Beyond the HITRAN pre-2004 format, there is one more tag for line mixing available in LBLRTM. This is a sign at the end of the line to indicate that the very next line gives line mixing information.
