Parameter estimation has been performed using LALInference\n[1] and a new sky map, LALInference.fits.gz,0, distributed via GCN\nNotice, is available for retrieval from the GraceDB event page:\n\nhttps://gracedb.ligo.org/superevents/S200208q\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 well fit by\nan ellipse with an area of 27 deg2 described by the following DS9\nregion (right ascension, declination, semi-major axis, semi-minor\naxis, position angle of the semi-minor axis):\n   icrs; ellipse(09h17m19s, -33d42m23s, 4d, 2d, 76d)\nMarginalized over the whole sky, the a posteriori luminosity distance\nestimate is 2142 +/- 459 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.
