Parameter estimation has been performed\nusing LALInference [1] and a new sky map, LALInference.fits.gz,0,\ndistributed via GCN Notice, is available for retrieval from the GraceDB\nevent page:\n\nhttps://gracedb.ligo.org/superevents/S200213t\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 2326 deg2.\nMarginalized over the whole sky, the a posteriori luminosity distance\nestimate is 201 +/- 80 Mpc (a posteriori mean +/- standard deviation).\n\nThis supersedes the previous Bilby analysis (GCN Circular 27092), which\nwas done with an outdated estimate of detector calibration uncertainty.\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo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.
