Observability Plots (ligo-skymap-plot-observability)

This is similar to ligo-skymap-plot-airmass, but integrated over the sky in order to create a bar chart and show the observability windows for several facilities at once.

Example

To make an observability plot for GW170817:

$ curl -O https://dcc.ligo.org/public/0146/G1701985/001/bayestar.fits.gz
$ ligo-skymap-plot-observability --site 'Las Campanas Observatory' 'SAAO' 'Siding Spring Observatory' --time 2017-08-17 bayestar.fits.gz -o bayestar.png

(Source code, png, hires.png, pdf)

Make an observability chart for a LIGO/Virgo/KAGRA probability sky map.
