Quickstart for Carsus

In this guide you will learn how to create atomic data files suitable for TARDIS.

Note:

Get familiar with the Notation in Carsus and learn how to correctly select ions.

Atomic Weights and Ionization Energies (NIST)

Download atomic weights and ionization energies from the National Institute of Standards and Technology (NIST).

Levels, Lines, Collisions & Cross-sections

Carsus supports three sources of energy levels and spectral lines: GFALL, CHIANTI and CMFGEN.

GFALL

The Robert Kurucz’s Atomic Linelist (GFALL) reader is the main source of levels and lines.

Warning:

Creating a GFALLReader instance is required.

[3]:
!wget -qO /tmp/gfall.dat https://media.githubusercontent.com/media/tardis-sn/carsus-db/master/gfall/gfall_latest.dat
[4]:
from carsus.io.kurucz import GFALLReader

gfall_reader = GFALLReader('H-Zn',
                           '/tmp/gfall.dat')
[     carsus.io.kurucz.gfall][WARNING] - A specific combination to identify unique levels from GFALL data has not been given. Defaulting to ["energy", "j"]. (gfall.py:113)

CHIANTI

The Chianti Atomic Database reader provides levels and lines but also collision strengths.

Note:

Creating a ChiantiReader instance is optional.

[5]:
from carsus.io.chianti_ import ChiantiReader

chianti_reader = ChiantiReader('H-He',
                               collisions=True,
                               priority=20)

By default priority parameter is set to 10. Increase this value if you want to keep CHIANTI levels and lines over GFALL.

CMFGEN

The atomic database of CMFGEN is a source of levels, lines and (optionally) ionization energies, photoionization cross-sections and collisions.

Note:

Creating a CMFGENReader instance is optional.

Warning:

Cross-sections require data from H 0, use this the reader with enough priority to select levels from this ion.

[6]:
from carsus.io.cmfgen import CMFGENReader

cmfgen_reader = CMFGENReader.from_config('Si 0-1',
                                         '/tmp/atomic',
                                         priority=30,

Zeta Data

Long & Knigge’s ground state recombinations fractions (\(\zeta\)).

[7]:
from carsus.io.zeta import KnoxLongZeta

zeta_data = KnoxLongZeta()

Nuclear decay data

Carsus also supports the decay radiation data of all the nuclides at the NNDC Archives. The ENSDF data is stored in CSV format in the repository carsus-data-nndc.

NNDC

The NNDCReader instance looks for the carsus-data-nndc repository in the local system at the path specified by the argument dirname. If the data is to be downloaded from the Github repository directly , the remote argument should be set to True.

Note:

Creating a NNDCReader instance is optional.

[8]:
from carsus.io.nuclear import NNDCReader

nndc_reader = NNDCReader(remote=True)
[     carsus.io.nuclear.nndc][WARNING] - Failed to clone the repository.
Check if the repository already exists at {DECAY_DATA_SOURCE_DIR} (nndc.py:44)

Create an Atomic Data File

Finally, create a TARDISAtomData object and dump the data with the to_hdf method.

[9]:

atom_data = TARDISAtomData(atomic_weights,
                           ionization_energies,
