Spectrum 1D brainstorm

Spectrum Class

Hierarchy:

inherits from NDData? SPectral super class?

API

call to interpolate?

Wavelength slicing?

WCS

Utils

##Notes from 2/8/2012 videocon

Discussion of utils: functions that don't use the Spectrum-ish class interface
Overview of nddata and WCS plans
Dimitri: Don't over-engineer? - start with Spectrum1D, add something in between
wolfgang: add a dummy-class to stand-in for simple WCS?
Discussion: Opt for no dummy-class for now
Adam: Have a "spectrum block"
Dimitri: require plot on Nddata?
Constructor form: init(self, disp, flux, meta, error, mask, units)
newspec=spec(x) w/ flux=spec(x,has_array=True) ?
There should be a spec.plot() (perhaps even in nddata?) *discussion of slice vs. interpolate syntax - conclusion is that something like spec.interpolate and spec.slice is better because its more explicit, but we should ask the list if we want to also have spec(...) or spec[...] options, after the methods are in place.
