qspec.analyze.King  (  a ,  m ,  x_abs = None ,  subtract_electrons = 0.0 ,  n_samples = 100000 ,  element_label = None  )[source]

Parameters:

andarray | Iterable

An iterable of the mass numbers of the considered isotopes with shape (k, ), where k is the number of isotopes.

mndarray | Iterable

The masses and their uncertainties of the isotopes 'a' (u). 'm' must have shape (k, 2).

x_absndarray | Iterable

The absolute values of the data vectors and their uncertainties corresponding to the mass numbers 'a'. If given, the 'x' and 'y' parameters can be omitted when fitting (in 'fit' and 'fit_nd') and is determined automatically as the difference between the mass numbers 'a' and 'a_ref'. Must have shape (k, n, 2) where n is the number of dimensions of the king plot.

subtract_electronsscalar

The number of electron masses that should be subtracted from the specified isotope masses. 'subtract_electrons' does not have to be an integer if the ionization energy must be considered.

n_samplesint

The number of generated samples for the monte-carlo routines.

element_labelstr

The label of the element to enhance the printed and plotted information.
