Gravitational Wave Skymap: GW170817
The probability contours of the location of the gravitational-wave
counterpart are shown below; the sky background can be changed with the
selector, and the interface allows arbitary zooming.
The 9 contour lines show percentiles of the probability density: the outermost line contains 90%
and the innermost contains 10%.
The three checkboxes below
are as follows:
- Coverage: shows if the ZTF survey has covered the skymap in the date range specified. Note that ZTF did not start until 20180527.
- Candidates: Shows the ZTF candidates surrounding the skymap and in a time window around the event time. The form fields are in days, as differences from the event time.
- Galaxies: Shows galaxies that may have the counterpart, with the size of the symbol as the 3D probability density at that galaxy position and distance.
