Summary of the Input Information

T0: 587509862.493000031 [MET] (2019-08-14T21:10:39.079 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/S190814bv/bayestar.fits.gz

FOV Check

The input source is in the BAT FOV with partial coding = 0.0163512377265
The input image does not overlaps with the BAT FOV
Max probability in LIGO map: 0.0005211866762242635
Sum of (BAT pcode)*(LIGO probability) of the entire LIGO map: 0.8163134674560691
The integrated LIGO localization probability that are in BAT FOV (with pcode > 10%): 0.9980342204613049
The integrated probability of Phil's convolved map that are in BAT FOV (with pcode > 10%): 0.999331357522133
The integrated LIGO localization probability that are outside of the BAT FOV (with pcode > 10%) but above the Earth's limb: 0.0010668375220460862

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.)

Survey data image search

We search for detections in the following images created using the survey data (obsid = 00010905033):
1. point_20192262103 (from T0-431.493 s to T0-131.493 s)  Sources with SNR(14-195 keV) > 3.5 
2. point_20192262108 (from T0-131.493 s to T0+168.507 s)  Sources with SNR(14-195 keV) > 3.5 
3. point_20192262113 (from T0+168.507 s to T0+420.507 s)  Sources with SNR(14-195 keV) > 3.5 


-----------------------------------------
In the lists above, only one source within the 90% LVG credible region:
RA = 14.495 deg
DEC = -26.613 deg
SNR (14-195 keV) = 5.6493 
Found in the image from point_20192262108
* Due to the low significance, this is likely from noise.
