Accommodate uncertainty on output

1

The new interface we've converged on (#231) uses the Features table as both input to setup a model, and _output_ to recover its results. Right now any parameter can have...

Convert Gauss1D, Drude1D to Area-Gauss/Drude-1D

6

Instead of using astropy's Gauss1D/Drude1D, use Area-Gauss/Drude-1D for the modelling (i.e. based on integrated strength).

Interface to MCMC codes

4

Would be great if we could use the same setup with an MCMC code. One obvious choice is the 'emcee' package. There is some work in astropy to enable this...

Fitting overlapping spectral segments

7

Currently, if we have overlapping spectral segments first the spectral segments are merged and then the resulting spectrum fit. This averages/ignores the fact that often the spectral resolutions between segments...
