38
39<P>The GEISA-97 individual lines spectroscopic databank management software
40is a FORTRAN software package requiring standard format input files or
41lines ( Ch&eacute;din et al., 1982, 1985; Husson et al., 1992 ). This software,
42implemented on the <A HREF="#INTER">GEISA Internet site for user's friendly
43on line use,</A> makes it possible various kinds of extractions such as:
44copy or creation of sub-files compatible whith the structure of the GEISA
45programs, analysis, list, extractions of transitions for one or several
46molecules (see Table&nbsp;1).</P>

692file occupies 127,352,061 bytes on the hard disk and the IBM-PC version
69347,167,430 bytes due to the use of an internal binary format for the data
694representation. Examples of the <A HREF="geisa_table5_gs03.html">direct image
695of the GEISA-97 cross-sections file lines records</A> are given in Table
6965. For each of the listed entries is provided the FORTRAN format of: the
697wavenumber, w (cm<SUP>-1</SUP>), in column one; the absorption cross-section
698value, s(w) (cm<SUP>2</SUP>molecule<SUP>-1</SUP>), in column two; the identification
699code M of the molecule, in column three, and the code C related with the
700atmospheric conditions (T and P), in column four. There is a total of 162<A HREF="geisa_table6_gs03.html">

705<P><FONT COLOR="#000000">To use and to manage the GEISA cross-sections
706files, two versions of the related software have been developed: the CROSS_U
707program to be used on the main frame systems and the CROSSUTI.EXE program
708designed for IBM-PC compatibles. The CROSS_U program allows the user to
709make extractions, from the whole file, the data being selected by the molecule
710type and the temperature and pressure experimental conditions. Graphic
711tools are included in the IBM-PC management software package, in the purpose
712of displaying selected cross-sections plotting information, as well as
713of making extraction of selected data. Both programs are equipped with
714an interactive user-friendly menu (Chursin et al., 1995, 1997). </FONT></P>
