Spectral stacking #40
Description
The basic Horne method will provide a single 1d spectrum for each prism/grism image. This step will combine these 1d spectra into a higher S/N spectrum. The user will be expected to specify which 2d prism/grism images to extract.
Given the different sub pixel phases, the wavelength vectors for each prism/grism image will be slightly different. This will require some methodology to sample the spectra onto the same fiducial grid.
