Problem on superevent aggregation of g-events (up to 5 sequence of alerts for the same Injection)
The following S-events did not properly aggregate in LLPIC cycle 4 (and following)
MULTIPLE ASSOCIATION
- CBC -- inj 1816 associated to ['S250525gx','S250525ha','S250525hb','S250525hc']
- BURST -- inj 2415 associated to ['S250526gr', 'S250526gq']
- BURST -- inj 2409 associated to ['S250522cw', 'S250522cv']
- BURST -- inj 2431 associated to ['S250522n', 'S250522m']
- O4 -- inj S240430ci associated to ['S250523am', 'S250523al']
Injection 1816 is snr=103.0 m1=4.5 m2=0.7 Mchirp~1.39 and in the LAST
LLPIC cycle generated five sequences of alerts S250810ho, S250810hr,
S250810hs, S250810ht, S250810hu:. Namely:
TIME OF THE ALERT UTC. SEVENT type of alert pipeline t_0 (UTC)
