no_fit_solution

sofia_redux.toolkit.resampling.no_fit_solution(set_index, point_index, fit_out, error_out, counts_out, weights_out, distance_weights_out, rchi2_out, offset_variance_out, get_error=True, get_counts=True, get_weights=True, get_distance_weights=True, get_rchi2=True, get_offset_variance=True, cval=nan)

Fill output arrays with set values on fit failure.

On fit failure, the output arrays are filled with certain values indicating that a fit is not possible. Count, and weight arrays contain zeros; the error, reduced chi-squared and offset variance are set to NaN; finally, the data array is set to cval, a user set float value.

Parameters:

set_indexint

An integer representing the data set for which a fit cannot be performed.

point_indexint

An integer representing the index of the fit coordinate at which the fit cannot be performed.

fit_outnumpy.ndarray (n_sets, n_coordinates)

The output fit values.

error_outnumpy.ndarray (n_sets, n_coordinates)

The output error values on the fit.

counts_outnumpy.ndarray (n_sets, n_coordinates)

The number of samples used to create the fit.

weights_outnumpy.ndarray (n_sets, n_coordinates)

The sum of full weights applied to samples in the fit.

distance_weights_outnumpy.ndarray (n_sets, n_coordinates)

The sum of only the distance weights applied to samples in the fit.

rchi2_outnumpy.ndarray (n_sets, n_coordinates)

The reduced chi-squared statistic of the fit.

offset_variance_outnumpy.ndarray (n_sets, n_coordinates)

The variance as derived from the offset of the fit coordinate from the sample distribution.

get_errorbool, optional

If False do not update error_out.

get_countsbool, optional

If ‘False’ do not update counts_out.

get_weightsbool, optional

If False do not update weights_out.

get_distance_weightsbool, optional

If False do not update distance_weights_out.

get_rchi2bool, optional

If False do not update rchi2_out.

get_offset_variancebool, optional

If False do not update offset_variance_out.

cvalfloat, optional

The fill value for data_out on fit failure.

Returns:

None

All arrays are updated in-place.
