Notes

This is a pure python routine.

The iso-electronic and adas208 are similar since the adas208 partial files are intended to be assembled into iso-electronic files. However the adas208 partial files contain multiple parent/level data which are separated in the iso-electronic files.

For iso-electronic files the indexing is embedded in the file name

        class    (indices 1 and 2)  units
        ----       ----     ----    -----
        acd        iprt     igrd    cm3/s
        scd        iprt     igrd    cm3/s
        ccd        iprt     igrd    cm3/s
        qcd        igrd     jgrd    cm3/s
        xcd        iprt     jprt    cm3/s
        prb        iprt             ergs/s cm3
        prc        iprt             ergs/s cm3
        plt        igrd             ergs/s cm3

For adas208 the name of the index depends on the type of adf10 file,

        class    (indices 1 and 2)  units
        ----       ----     ----    -----
        acd        iprt     igrd    cm3/s
        scd        iprt     igrd    cm3/s
        ccd        iprt     igrd    cm3/s
        qcd        igrd     jgrd    cm3/s
        xcd        iprt     jprt    cm3/s
        prb        iprt             W cm3
        prc        iprt             W cm3
        plt        igrd             W cm3
        met        igrd               -

For adas204 the useful adf10-style files are,

        class    (indices 1 and 2)  units
        ----       ----     ----    -----
        acd        iprt     igrd    cm3/s
        scd        iprt     igrd    cm3/s
        prb        iprt     igrd    W cm3
        pcasbin    iprt     igrd    W cm3

and pcasbin is not currently an iso-electronic adf10 class.

For adas204 files is not possible to determine from the file structure or contents the difference between acd and ccd files or prb and prc files so the 'class' is set as 'acd/ccd' or 'prb/prc'.

Note the different units for temperature, density and power between the variants.

Version History

  • Add information dictionary and list of production dates to the iso-electronic variant.
  • Ad an example.

Example

Get the data for the ionization data from the He-like metastable and print the elements in the file (iz1 is the recombining stage) and the dates when each element was generated.

>>> import adas as adas
>>> file='/home/adas/adas/adf10/scd96/pj#scd96_he12.dat'
>>> fulldata=adas.xxdata_10(file)
>>> fulldata['iz1'], fulldata['dates']
(array([ 1.,  2.,  3.,  5.,  6.,  7.,  9., 13.]),
 ['01.11.99',
  '30/10/02',
  '20/02/06',
  '02.11.99',
  '03.11.99',
  '25.07.01',
  '20.12.00',
  '13/03/13'])

Note that the routine prints 'iso-electronic variant' to the screen.
