spectral_rectify_interp#

excalibuhr.utils.spectral_rectify_interp(im_list, badpix, trace, slit_meta, reverse=False, debug=False)[source]#

Correct for the slit-tilt by interpolating to a pixel-grid

Parameters:

  • im_list (array) – input image or a list of image and variance to be corrected

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

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

  • slit_meta (array) – polynomials that describing the slit curvature as a function of the dispersion axis

  • reverse (bool) – if True, interpolate back to the tilted slit

Returns:

im_rect_spec – rectified images where the slit image is vertical on detector

Return type:

array
