  1. These files are in the same format as GENLN2 non-LTE input data supplied by IAA Granada, Spain.
  2. In normal use, only the vibrational temperatures are supplied since rotational LTE is assumed. If ROTID is specified then Rotational non-LTE is implemented for particular lines (ignored in RFM versions before v4.26).
  3. If a purely vibrational temperature is specified for a level (no ROTID field) this becomes the default for any transitions for which no rotational ID is specified.
  4. A negative value of the vibrational quantum number IVSGQ for the upper energy of a transition results in the RFM only calculating the source function in LTE, while assuming line strength and absorption are determined by LTE (ie kinetic temperature) (v4.26 onwards)
