COMMENTS:        This is an image trigger.  (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=15314=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: X_1745.6-2901,   delta=0.040 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This trigger occurred at longitude,latitude = 60.63,16.92 [deg].  
COMMENTS:           
COMMENTS:        NOTE:  This location is less than 10arcmin from the boresight -- Swift was already looking at this source.
