saltfppipe

Welcome to the documentation for saltfppipe, a data reduction pipeline for the SALT Fabry-Perot system.

Note

If you make use of this code, please include the following in your acknowledgements section: “This research made use of saltfppipe, a data reduction package for the SALT Fabry-Perot.”

This code is built atop IRAF/Pyraf, PySALT, Astropy, matplotLib, and SciPy. You should also cite/acknowledge these packages as appropriate.

Note

This software was developed primarily to reduce FP data taken in the medium-resolution mode and most of the testing has been with that data. It has been used to reduce low-resolution data to some degree of success. This code is not intended to be used on duel-etalon high-resolution data.
