Function adas.read_adf24

def read_adf24(file=None, block=1, energy=[0.0], return_info=False)

Interpolate/extrapolate charge exchange cross section data from adf24 files.

Parameters

file : str
full names of ADAS adf24 file
block : int
selected block
energy : float, array
energies requested (eV/amu)
return_info : bool
If True also return a dictionary of information on the peocess. The default is False.

Returns

sigma : float, array
cross section (cm**2).
info : dict
information from header line of the selected block in adf24 file
'donor'    : donor species
'receiver' : receiver species

Notes

Calls a fortran based shared object file - not pure python.
