COMMENTS:        RXTE-PCA GRB Coordinates.  
COMMENTS:        The RXTE-PCA observation started at 98/06/11 04:47:13.00 UT.  
COMMENTS:        RXTE/PCA detected two sources during the  
COMMENTS:        follow-up  observation for GRB980611.  
COMMENTS:        One source is slightly out of the  
COMMENTS:        region covered by scans (7deg[RA] x 8deg[Dec]  
COMMENTS:        was coverd). So it's impossible to determine  
COMMENTS:        the position.  The probable position is   
COMMENTS:        RA=279 & Dec=56 or west to this position  
COMMENTS:        (larger RA).  But it's more than 4.2 degree  
COMMENTS:        away from the BATSE LOCBURST position.  
COMMENTS:        The other source is located at:  
COMMENTS:        R.A.: 18h25m.88 +/- 0m.96   
COMMENTS:        Dec.: 53o51m.6 +/- 9m.6  
COMMENTS:        and the flux level was:  
COMMENTS:        Flux:  6.31 +/- 0.85 c/s in Std2 Layer1 2-10 keV   
COMMENTS:        The errors were estimated from change in
