Below is a FORTRAN program that reads the CH4 database

      Program Read 
c...Read the half-widht and line shift databases in the 2008 CH4 format
      real*8 FF
      character*15 Avibu,Avibl,Rotu,Rotl
c...  FF    - frequency of the transition in cm^-1
c...  Avibu - upper vibration state HITRAN format
c...  Avibl - lower vibration state HITRAN format
c...  Rotu  - upper state rotation quantum number HITRAN format
c...  Rotl  - lower state rotation quantum number HITRAN format
c...  g     - half-width in units of 10^-3 cm^-1/atm
c...  ge    - error in the half-width (same units as g)
c...  xn    - temperature dependence of half-width, exponent of power law model
c...  xne   - error in temperature dependence
c...  d     - line shift in units of 10^-3 cm^-1/atm
c...  de    - error in the line shift (same units as g)
c...  xnd   - temperature dependence of line shift (not currently used)
c...  xnde  - error in temperature dependence
c...  ISO   - Isotopologue code, HITRAN convention
c...  IRefx - Reference of the data, see accompanying reference list
