# Data release for "Properties of the binary neutron star merger GW170817"
DCC document https://dcc.ligo.org/LIGO-P1800061/public

The IPython notebook `Data Release Tutorial.ipynb` provides example code to 
read and plot the data files listed below.

## GW170817_PSDs.dat

Values of the LIGO_Hanford, LIGO_Livingston and	Virgo PSDs (1/Hz) as a function 
of frequency (Hz) corresponding to figure 1 of the paper. See the section "PSDs"
of `Data Release Tutorial.ipynb` for an example plot.

## high_spin_PhenomPNRT_posterior_samples.dat.gz and low_spin_PhenomPNRT_posterior_samples.dat.gz

Posterior samples for the PhenomPNRT approximant (see paper for details). See 
the section "Posterior samples" of `Data Release Tutorial.ipynb` for an example 
on how to read and plot those files. Those posterior samples are used in 
Table II and figures 4 to 12.

## figure_3.tar.gz

Data for figure 3, including a README.md file. See the section 
"Sky Localization" of `Data Release Tutorial.ipynb` for an example how to read 
and plot this data. Note that this depends on `healpy` for which the standard 
`pip install` may be temporarily broken on some systems.

## figure_4.tar.gz

Data for figure 4, including a README.md file. See the section 
"Distance and Inclination" of `Data Release Tutorial.ipynb` for an example how 
to read and plot this data.

## Other figures

Work is in progress to extend the examples provided here to the other figures 
of the paper.
