real(kind=kind_phys), dimension(ng05, mfr05), public forref
 the array forref contains the coefficient of the water vapor foreign-continuum (including the energy term). the first index refers to reference temperature (296,260,224,260) and pressure (970,475,219,3 mbar) levels. the second index runs over the g-channel (1 to NG05=16).
 
real(kind=kind_phys), dimension(ng05, msa05), public absa
 the array absa(NG05,585) = ka(NG05,9,5,13) contains absorption coefs at the NG05=16 g-intervals for a range of pressure levels > ~100mb, temperatures, and ratios of water vapor to co2. the first index in the array, js, runs from 1 to 9, and corresponds to different water vapor to co2 ratios, as expressed through the binary species parameter eta, defined as eta = gas1/(gas1+(rat)*gas2), where rat is the ratio of the reference mls column amount value of gas1 to that of gas2. the 2nd index in the array, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 1-5 means that the data are for the corresponding temperature of tref-30, tref-15, tref, tref+15, and tref+30, respectively. the third index, jp, runs from 1 to 13 and refers to the reference pressure level (e.g. jp = 1 is for a pressure of 1053.63 mb). the fourth index, ig, goes from 1 to NG05=16, and tells us which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(ng05, msb05), public absb
 the array absb(NG05,1175) = kb(NG05,5,5,13:59) contains absorption coefs at the NG05=16 g-intervals for a range of pressure levels < ~100mb, temperatures, and ratios of h2o to co2. the first index in the array, js, runs from 1 to 5, and corresponds to different gas amount ratios, as expressed through the binary species parameter eta, defined as eta = gas1/(gas1+rat*gas2), where rat is the ratio of the reference mls column amount value of gas1 to that of gas2. the second index, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 1-5 means that the data are for the corresponding temperature of tref-30, tref-15, tref, tref+15, and tref+30, respectively. the third index, jp, runs from 13 to 59 and refers to the reference pressure level (e.g. jp = 13 is for a pressure of 95.5835 mb). the fourth index, ig, goes from 1 to NG05=16, and tells us which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(ng05, msf05), public selfref
 the array selfref contains the coefficient of the water vapor self-continuum (including the energy term). the first index refers to temperature in 7.2 degree increments. for instance, jt = 1 refers to a temperature of 245.6, jt = 2 refers to 252.8, etc. the second index runs over the g-channel (1 to NG05=16).

 planck fraction mapping level : p = 0.2369280 mbar, t = 253.60 k
