Reorganize and add topic keywords

[kelle]

Reorganize and publish list of keywords. Reorganize = separate out science topics vs coding topics.

Also make sure keywords are in the UAT.
(http://astrothesaurus.org/thesaurus/alphabetical-browse/ and http://astrothesaurus.org/thesaurus/autocomplete-widget/).

I see three major categories, but I don't know the best names for them. Here are some examples:

• Category 1 (package): astroquery, obsplan, matplotlib, scipy
• Category 2 (function): contour plots, histogram, errorbars, fitting
• Category 3 (science): radio, xray, physics, dynamics

One question is whether or not to divide up astropy project packages from the rest. I lean towards yes. So maybe: "Python Package" and "Astropy Package"?

I've added a Keyword Table tab here: https://docs.google.com/spreadsheets/d/1JmOF82Zmrs397wLwAmmL1rgDSsvP6Z4fLMr0hV5ZIb4/edit#gid=953884002

Here's what it looks like but please edit/comment on the google doc.

astropy package	python package	task	science	companion content
astroquery	matplotlib	contour plots	astrodynamics	Carroll & Ostlie
coordinates	numpy	data cubes	stellar photometry	Cox
obsplan	scipy	fits header	stellar physics	George H. Rieke
reproject		fits image	radio astronomy	McLean
table		fits table	astrostatistics	Howell
		model fitting	x-ray astronomy	Tennyson
		file input/output		Emerson
		histogram		Cassinelli & Lamers
		errorbars		Binney & Tremaine
		OOP
		plots
		spectroscopy
		time series
		units
		Vizier

as keywords get updated, the website needs to be updated by hand: https://github.com/astropy/astropy-tutorials/blob/master/tutorials/themes/tutorials-theme/tutorialfilters.html

Should we consider having a separate keyword category for visualization? This category would include the currently used keywords: scatter plot, contour plot, error bars, color bar, and histogram.

@stephtdouglas and I have made lots of progress on the keywords during PyAstro19! One area we didn't touch much was the Companion Content keywords. They still need attention.

Things still left to do:

• companion content
• decide on order of keywords and reorder. Alphabetical or by decreasing use.
• add number of uses to each keyword. (eg., coordinates (5))
• add viz category?
• get rid of file input/output?
