find_spaxel_flux

jwst.cube_build.cube_lib.find_spaxel_flux(spaxel_iflux, spaxel_flux, spaxel_weight, spaxel_var)[source]

Calculate the final normalized flux and variance for each spaxel.

Normalizes the weighted flux and variance arrays after mapping overlap between the detector array and the sky. Spaxels with no contributing points (where spaxel_iflux == 0) are ignored to prevent division-by-zero errors.

Parameters:

spaxel_ifluxnumpy.ndarray: Array containing the counts/number of detector elements contributing to each spaxel.
spaxel_fluxnumpy.ndarray: Array of weighted cumulative flux values. Modified in-place.
spaxel_weightnumpy.ndarray: Array of total weights accumulated for each spaxel.Modified in-place.
spaxel_varnumpy.ndarray: Array of cumulative variance values. Modified in-place.

Returns:

spaxel_fluxnumpy.ndarray: Array of weighted cumulative flux values. Modified in-place.
spaxel_varnumpy.ndarray: Array of cumulative variance values. Modified in-place.
