Parameter estimation has been performed using\nLALInference [1] and a new sky map, LALInference.fits.gz, distributed\nvia GCN Notice, is available for retrieval from the GraceDB event page:\n\nhttps://gracedb.ligo.org/superevents/S190521g\n\nLALInference.fits.gz is the preferred sky map at this time.\nThe 90% credible region is 765 deg2. Marginalized over the whole sky,\nthe a posteriori luminosity distance estimate is 3931 +/- 953 Mpc\n(a posteriori mean +/- standard deviation).\n\nFor further information about analysis methodology and the contents\nof this alert, refer to the LIGO/Virgo Public Alerts User Guide\n<https/emfollow.docs.ligo.org/userguide/>.\n\n[1] Veitch et al.
