write:

Analysis of the full data set derived from the HETE Soft X-ray Camera 
(SXC) has resulted in a revised location for GRB020813(=H2262; 
Villasenor et al, GCN Circular #1471). The revised SXC location can 
be expressed as a 90% confidence circle that is 50 arcseconds in 
radius (due entirely to systematic errors) and is centered at:

RA = 19h 46m 41.8s, Dec = -19o 35' 39" (J2000)

We conclude that the Fox et al (GCN Circular #1470) afterglow 
candidate for GRB020813 lies 26 arcseconds from the SXC location, 
well within the error circle reported here.
