extract_blaze

excalibuhr.utils.extract_blaze(im, badpix, trace, f0=0.5, fw=0.48, sigma=3)

Collpase 2D image along the cross-dispersion direction in an order-by-order basis.

Parameters:

• im (array) – input flat image to be normalized

• badpix (array) – bad pixel map corresponding to the input image

• trace (array) – polynomials that delineate the edge of the specific order

Returns:

blaze_orders – 1D blaze function of each order

Return type:

array
