The GEISA 2011 sub-database on line transition parameters
GEISA 2011 format for line transition parameters
Illustration of the format used for the line transition parameters archive in the 2011 edition of GEISA :
This format includes 31 spectroscopic line parameters representing 252 characters record per entry. The spectroscopic line parameters are listed in the 31 columns of the first line of Table -1- and their description is given below. For each parameter, the field length and the FORTAN format descriptor are given in lines 2 and 3, with associated counting of the records (in blue) in lines 4 and 5,
Some modifications have been brought to the GEISA 2003 format , i.e.:
- Lengths of fields E1, E2, E3, E4, N, O, N’, O', have been extended (high-lightened in pale red)
- Fields P and Q have been suppressed (related with non GEISA references)
- Standard default values have been adopted for each parameter and for the whole database as described .
It has to be noticed that:
- Fields K and L (high-lightened in grey) are HITRAN specific for the users’ easier possible interface between the two databases.
- Value in field M is given only if directly provided by the author of the spectroscopic line entry.

Identification of vibrational quantum number implementations in fields E1 and E2:
Please see Table -2- in the attached document for quantum number identification digits in the E1 and E2 fields of the format (positions illustrated by yellow cells) and specific of each molecule (ordered in the GEISA internal molecule numbering). The illustration corresponds to the possible maximum number of digits, for a given transition.
In case of non identified vibrational transitions, an additional line format description, with all of its 25 cells in grey colour, has been added.
See section “Overall description of available vibrational transitions” for detailed lists, per molecule, of vibrational transitions and associated complementary information.
Those descriptions are intended to facilitate the use of the Transition Analysis option in the “database access” section.
