Function adas.xxdata_35

def xxdata_35(file=None)

Reads an adf35 energy transmission filter file (EEDF) file and returns all of its contents in a dictionary.

Parameters

file : str
full name of ADAS adf35 file

Returns

fulldata : dict
contents of the adf35 file
    'file'       :  adf35 filename
    'edge'       :  array of energy edges
                      None, scalar or array(nedges)
    'energy'     :  energy points of tabulation (eVV)
                      array(nenergy)
    'trans'      :  log10 of transmission fraction
                      array(nenergy)

Notes

Pure python routine.
