Parameter estimation has been performed using\nLALInference [1] and a new sky map, LALInference.fits.gz,0,\ndistributed via GCN Notice, is available for retrieval from the\nGraceDB event page:\n\nhttps://gracedb.ligo.org/superevents/S191216ap\n\nThe preferred sky map at this time is LALInference.fits.gz,0. For the\nLALInference.fits.gz,0 sky map, the 90% credible region is 253 deg2.\nMarginalized over the whole sky, the a posteriori luminosity distance\nestimate is 376 +/- 70 Mpc (a posteriori mean +/- standard deviation).\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo Public Alerts User Guide\n<https://emfollow.docs.ligo.org/userguide/>.\n\n [1] Veitch et al.
