Analysis of the full data set derived from the HETE Soft X-ray Camera
(SXC) has resulted in a revised location for GRB021004(=H2380;
Shirasaki et al, GCN Circular #1565). The revised SXC location can be
expressed as a 90% confidence circle that is 62 arcsec in radius and
is centered at:
RA = 00h 26m 55.7s, Dec = +18d 56' 18.6" (J2000)
This revised SXC localization is shifted 38 arcsec with respect to,
but lies fully within, the original 120 arcsec radius SXC error
circle reported by Shirasaki et al in GCN1565. The fading optical
transient reported by Fox in GCN1564 is 40 arcsec from the center of,
and is within, this revised SXC error circle.
