Description
            CelestLab is a library of space flight dynamics functions written in Scilab. 
This library has been developed by CNES (Centre National d’Etudes Spatiales)
for mission analysis purposes. It is used for trajectory analysis and orbit
design for various types of missions (around Earth, interplanetary...).  

CelestLab includes about 200 functions that allow mission designers to perform
various tasks such as: orbit propagation, manoeuvre computation, change of
reference frames and coordinates, etc...

constant must be moved also in a function

r = celest_getConstant('mu')

Comment from Alain Lamy -- March 25, 2011, 03:55:28 PM    
Some comments : 

-> The reason some variables exist in the working environment is that: 
- a certain number of functions have default arguments (planet radius and other similar 
data), 
- we did not want the user to have to care too much about these arguments in order to 
simplify the use of CelestLab. 

-> There is a function that initializes the variables (CL_init) but it initializes them 
all at once. 

-> It could be possible to create a function in place of %CL_home (in particular) as its 
use is mostly internal to CelestLab

-> Concerning the other data, we'll have to think about it a bit, as we have to care 
about : 
- how easy it is to obtain useful results with CelestLab, 
- the compatibility between CelestLab versions, 
- the complexity of CelestLab itself, 
- ...
