Correct sky subtraction with PypeIt #1779

Closed jesusgomez2001 closed 7 months ago

I am reaching out for assistance as a novice user of PypeIt, and I apologize in advance if my question seems too basic.

I am currently working with VLT-Xshooter files that have been processed using the corresponding pipeline. However, I am encountering challenges with the sky subtraction, as evident in the attached 2D images of the UVB and VIS spectra.

I am wondering if it is possible to use PypeIt to effectively subtract the sky background, correct for spectrum curvature, and generate a 1D flux versus wavelength spectrum from these provided images.

My intention is not to perform the entire reduction using PypeIt but to focus solely on this specific aspect. I would greatly appreciate any guidance or instructions on how to achieve this with PypeIt. Additionally, if there are specific parameters or steps I should consider, please provide insights to help me overcome these challenges.

Thank you very much in advance for your assistance, and I sincerely apologize for any inconvenience.
