The GEISA 2015 sub-database on line transition parameters
GEISA 2015 format for line transition parameters
Illustration of the format used for the line transition parameters archive in the 2015 edition of GEISA :
The format of each entry is described in the following Table 1.
Each entry is a 252 character record to describe the 31 spectroscopic line parameters.
First line of Table 1: the 31 Spectroscopic line parameters are listed in the 31 columns and their description is given below.
Line 2 and line 3 display the field length and the FORTAN format descriptor, respectively.
Line 4 displays the standard default values associated to each parameter.
Line 5 displays a cumulative index indicating the position of the last character of the record associated to each of the 31 spectroscopic line parameters.
The standard default values for fields «O’», « T » and « T’ », have been set to “zero”. These modifications, since the GEISA-2011 edition, were made to avoid potential misunderstanding and thus improper use of these parameters in some applications especially related to forward radiative transfer.
It has to be noted 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:
See Overall description of available vibrational transitions for quantum number identification digits in the E1 and E2 fields of the format (positions illustrated by character *) and specific of each molecule (ordered in the GEISA internal molecule numbering). The illustrations correspond to the possible maximum number of digits, for a given transition.
Those descriptions are intended to facilitate the use of the Transition Analysis option in the “database access” section.
