[vsnet-grb-info 766] Re: GRB030227: refined INTEGRAL position

Dear Dr. Gotz and all,

In GCN 1896;

  Is this position certainly on J2000, not on the current equinox?
The position on GCN 1895 was memtioned as J2000, but it coincidented
the position on the current equinox reported in :

>TITLE:          GCN/INTEGRAL NOTICE
>NOTICE_DATE:    Thu 27 Feb 03 09:29:48 UT
>NOTICE_TYPE:    INTEGRAL Offline
>TRIGGER_NUM:    214,   Sub_Num: 0

  If it is certainly on J2000.0, the refined error circle (3' radius)
intersects the initial one (5' radius).  

Sincerely Yours,
