Key

Data Type

Description

input_parameters

string

the FEFF input settings used in the computation of the spectrum.

xas_id

string

unique id for each spectrum, e.g. 'mp-505011-28-XANES-K'.

spectrum_type

string

type of XAS e.g. 'XANES'.

edge

string

absorption edge e.g. 'K'.

mp_id

string

mp id of the structure.

absorbing_atom

string

site index of the absorbing site in the structure.

structure

string

the structure in dictionary format (can be loaded as a Structure object in pymatgen).

spectrum

float

array of shape (100, 6) where each column means the following(in that order):Energy(eV), Energy with respect to the Fermi level(eV), Wave number, μ(total absorption coefficient), μ0(the background absorption coefficient), x(normalized finestructure)
