For the\nLALInference.fits.gz sky map, the 90% credible region is 4480 deg2.\nMarginalized over the whole sky, the a posteriori luminosity distance\nestimate is 201 +/- 81 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.
