Loading and fitting a line in an SDSS spectrum with specutils #440

Open eblur opened 4 years ago

I produced two notebooks from the Astropy Spectroscopy Sprint (April 6 - 10) that are ready for review. When we are happy with them, I'll submit a pull request.

Part 1: Load, Plot, and Smooth an Optical Spectrum from SDSS

Part 2: Measure Properties of a Spectral Emission Line

From #260 , we want this tutorial to check all these boxes:

Measure EW of high res vs low res version.

[ ] how to access spectrum? astroquery? high res spectrum with uncertainty.
[ ] custom loader
[ ] generate the Spectrum1D object.
[ ] something about noise - can generate our own unc attribute of Spectrum1D.
[ ] spectrum arithmetic.
[ ] spectrum regions
[ ] Deconvolve - smoothing.
[ ] fit continuum, normalization.
[ ] how to measure an EW already on Getting Started
[ ] line flux.

I made a draft tutorial here which might be helpful: https://colab.research.google.com/drive/1QQqFwv6QKK7wc1wiLq0KnjLncMeDBUUs
