| Description |
|
Using 2D merged arc images for testing, subtract a subset of fibers from the others. Check the residuals to determine subtraction performance. The 2D model, similarly to PIPE2D-329, can be derived from a combination of:

My understanding is that the continuum will be handled by the 1D sky subtraction module. I've always considered the goal of 2D sky subtraction to be to get rid of the wings of the brightest sky lines so they don't adversely affect the neighbouring fiber's spectrum, and the continuum doesn't play into that. Also, if we were to do it as part of the 2D module, we'd be using 1D methods anyway, so I don't see the point in doing that twice. |

Actually, to measure the line intensities correctly, we will likely need to measure the continuum. But for this proof-of-concept exercise on non-HgAr arcs, let's ignore the continuum. |

This is more work that I completed last year but didn't have a chance to wrangle onto master. |

Merged to master. |
