Transient Analysis Summary

Summary of the Input Information

T0: 587683356.453999996 [MET] (2019-08-16T21:22:13.027 UTC)
Search time window: T0 +/- 100.0 s
Input source: RA=0.0, DEC=0.0 (source location is randomly seleected, since the true location is unknown.)
Input image: /local/data/bat2/batusers/batgroup/BAT_GW/results/GBM-190816/GBM-190816-with-LV-v1.fits.gz

FOV Check

The input source is out of the BAT FOV
The input image does not overlaps with the BAT FOV
The integrated LIGO localization probability that are in BAT FOV (with pcode > 10%): 0.22463381278725683
The integrated LIGO localization probability that are outside of the BAT FOV (with pcode > 10%) but above the Earth's limb: 0.6284702970351163

BAT FOV 10s ago
BAT FOV 10s after

RED: BAT FOV (the brighter/whiter color refers to higher partial coding fraction).

YELLOW: Earth

BLUE: LIGO probability map

GREEN STAR: Input source (location is randomly seleected unless the true source location is available.)

Raw Light Curves

Quad-rate light curves (with 1.6 s time bin)

64-ms light curves

1-s light curves
