Gravitational Wave Skymap: S200208q_1

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.
