Parameter estimation has been\nperformed using Bilby [1] and a new sky map,\nBilby.offline0.multiorder.fits,0, distributed via GCN Notice, is\navailable for retrieval from the GraceDB event page:\n\nhttps://gracedb.ligo.org/superevents/S231001aq\n\nFor the Bilby.offline0.multiorder.fits,0 sky map, the 90% credible\nregion is 3181 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 4425 +/- 1946 Mpc (a posteriori mean\n+/- standard deviation).\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo/KAGRA Public Alerts User Guide\nhttps://emfollow.docs.ligo.org/userguide/.\n\n\n [1] Ashton et al.
