Records the path of DExxx ephemeris files
ephem = CL_ephDE_setPath(dpath)
Records the path of the directory where DExxx ephemeris files are to be found. If the path is an empty string (""), "de405" in CelestLab data directory is used.
The result is returned in a Scilab stucture ephem that can be used by the function CL_ephDE_getPVA.
Notes:
- The format of the ephemeris file is specific to CelestLab.
- The difference with CL_ephDE_load or CL_ephDE_loadT is that the ephemeris files are not loaded into memory. Only a file descriptor is. The ephemeris files will be loaded in memory as needed, at least once per call to CL_ephDE_getPVA for instance. If the function CL_ephDE_getPVA has to be called multiple times, it is more efficient to load the ephemeris files into memory by using CL_ephDE_load or CL_ephDE_loadT.
(string) Path of ephemeris directory. Default value: "" (see above). (1x1)
