KMOS tools Documentation

These are some key python routines used to post-process VLT/KMOS data in the KLASS VLT Large Program (196.A-0778).

This not complete, tested on other systems, or very well-supported… If you have problems I encourage you to fix them and submit a pull request :)!

If you find these useful please cite the KLASS survey papers: Mason et al. (2017) and Mason et al. (2019) where I describe some of these methods.

I thank Trevor Mendel, Owen Turner and the ESO helpdesk and KMOS team for many tips. I also benefited from reading the excellent discussion of sky residual cleaning in Stott et al. (2016) which others may find helpful. I made this package and documentation with a lot of help from this great tutorial.
