Function adas.adf04_remove_levels

def adf04_remove_levels(file=None, level_list=None, remove_untied=False, ndlev=4500, ndtrn=150000)

Removes the user supplied levels from an adf04 file. The result is returned as an adf04 fulldata dictionary.

Parameters

file : str
full name of ADAS adf04 file
level_list : int, list or array
The list of levels to be purged. Not needed if remove_untied is True.
remove_untied : bool
if set to True, remove untied levels.
ndlev : int, optional
maximum number of levels in adf04 file - defaults is 4500
ndtrn : int, optional
maximum number of transitions in adf04 file - default is 150000

Returns

fulldata : dict
adf04 dictionary.

Notes

Pure python code but calls routines which are dependent on fortran.

Only excitation data is retained - R, S and H levels are dropped for this first version.

Note that the configuration and transition indices start at 1, as in the adf04 definition, and not at 0 (python-like).
