As a result of alerts 969 and 970, which had att_flag='TM/AUX MISMATCH' it was decided not to forward any alerts in such situation. Implemented in the next IBAS installation.

OFFLINE 596/1 2003-05-01 03:10:18 12.9286.3776.3073.0GRB030501, GCN NOTICES
this was the first GRB localized in real time for which the criteria for automatic distribution were met. First optical followup observations started 7 seconds after WAKEUP alert 596/0 while GRB was still active in gamma range (see GCN notices for more details).
WAKEUP 596/0 2003-05-01 03:10:18 10.0286.3826.3414.4 
OFFLINE 566/1 2003-04-17 06:24:20 10.5299.64335.262-4.3Cyg X-1, ibas computed position was 4.4 arcmin from the object's true position, which was slightly above the threshold level for this trigger (4.1arcmin). Software was modified and the threshold was raised to 6arcmin.
WAKEUP 566/0 2003-04-17 06:24:20 10.5299.64335.2624.3 
OFFLINE 484/1 2003-03-31 02:38:12 10.5266.570-32.240-4.3IGR J17464-3213, not on a blacklist at the trigger time, source added later to the blacklist
WAKEUP 484/0 2003-03-31 02:38:12 10.5266.570-32.2404.3 
OFFLINE 343/0 2003-03-20 10:11:40 13.0267.929-25.3095.0GRB030320, GCN NOTICES
WAKEUP alert not generated/dispatched in real time due to low sigma value. GRB very far from the axis, almost at the FOV limit.
WAKEUP 233/0 2003-03-02 12:38:52 12.7186.653-62.7725.0not a grb, false trigger.
After this event, it was decided to distribute special OFFLINE alerts which retract GRBs. The alerts which retract GRB have grb_pos_err < 0.
OFFLINE 214/0 2003-02-27 08:42:16 15.874.32420.4855.0GRB030227, OT, XRAY, GCN NOTICES
WAKEUP alert with correct GRB position distributed in real time internally in ISDC. WAKEUP alert not distributed in real time to the outside world because of ongoing Crab calibration observation.
OFFLINE 101/0 2003-01-31 07:39:10 8.0201.78030.77030.0GRB030131, GCN NOTICES
WAKEUP alert distribution in real time was cancelled by IBAS alertd program based on the fact that most of the burst occured during the S/C slew.
This was the first GRB with distribution of IBAS alerts to the registered clients enabled (clients received OFFLINE alert)
