Mention GW candidate anyways in low significance joint circulars

See this new prospective example text:

Based on the analysis of gravitational-wave data alone, this candidate does not meet our criteria for a high-significance public alert as its false alarm rate is estimated by the online analysis to be 0.00012 Hz or about one in 2 hours. However, a search performed by the RAVEN pipeline found a significant coincidence between this candidate and 776849714. The event’s properties can be found at this URL:
