interpolate_onto_grid

jwst.pathloss.pathloss.interpolate_onto_grid(wavelength_grid, wavelength_vector, pathloss_vector)

Interpolate pathloss value onto grid.

Get the value of pathloss by interpolating each non-NaN element of wavelength_grid into pathloss_vector using the index lookup of wavelength_vector. Pixels with wavelengths outside the range of the reference file should have a correction of NaN.

Parameters:

wavelength_gridndarray

The 2-D grid of wavelengths for each science data pixel

wavelength_vectorndarray

The 1-D vector of wavelengths

pathloss_vectorndarray

Corresponding 1-D vector of pathloss values

Returns:

pathloss_gridndarray

Grid of pathloss corrections for each non-NaN pixel
