COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=10762=sgr1935p2154,   delta=0.008 [deg].  
COMMENTS:        This matches a source in the ground catalog: sgr1935p2154,   delta=0.008 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This trigger occurred at longitude,latitude = 145.30,-6.68 [deg].  
COMMENTS:           
COMMENTS:        NOTE:  This location is less than 10arcmin from the boresight -- Swift was already looking at this source.  
COMMENTS:           
COMMENTS:        NOTE: This BAT event is spatially(0.00<0.1deg) coincident with the SWIFT_BAT event (trignum=687123).
