Introduction
------------

KSPECTRUM is a code that will compute high-resolution spectrum
(ka vs nu) from public line-by-line databases, for any thermodynamical
conditions (temperature, pressure), and for any gas mixture, with a full
control of the accuracy of the results. These spectrum can be used,
for instance, in order to produce k-distribution data sets that are very
appreciated for radiative transfer simulations.


Features
--------

* high-resolution spectrum: each line is well represented
* will work for (almost) any gas mixture
* Full control of accuracy: the user specifies the uncertainty over the results
* NO line selection: the contribution of all transitions is effectively computed
& NO line truncation => no need to use an ad-hoc continuum
* will work even on low-memory systems (<1Gb RAM)
* Possibility to resume an interrupted computation.


Teams
-----

KSPECTRUM was developped by the LAPLACE (Toulouse).
Contributors to the project include
Richard Fournier, Stéphane Blanco, Vincent Eymet.

Revisions by Markus Scheucher at DLR / TU Berlin (Germany) 
led to Version Htr16.


Requirements
------------

* a fortran 77 compiler
* basic unix/linux commands
* mpich2


Installation + use
------------
See the manual.
