 +==== Download software ====

 +{{:lblod4esas_v01.tgz|}} 
 + 
 +==== Installation ==== 
 + 
 +Prerequisites:  
 +  * Python (version 2.5 or better)  [[http://www.python.org|python.org]] 
 +  * numpy — Numeric Python [[http://www.numpy.org|numpy.org]] 
 +  * Additionally (depending on some of the options set): 
 +    * scipy — Scientific Python [[http://www.scipy.org|scipy.org]] 
 +    * matplotlib 
 +  * (Obviously you also need a copy of the Hitran or Geisa line parameter databases) 
 + 
 +  - Save the package at some convenient place and unpack it: ''tar xvfz lblod4esas.tgz'' 
 +  - Ideally add the ''bin'' directory to your system search ''PATH'' 
 +  - If you are reading user guide's etc: in your browser open the ''index.html'' file in the ''doc'' directory;\\ Otherwise just ''extract'' line parameters from HITRAN and GEISA, then compute optical depth via cross sections by ''lbl2od''
