Parameter\nestimation has been performed using LALInference [1] and a new sky\nmap, lalinference.fits.gz, is available for retrieval from the\nGraceDB event page:\n\nhttps://gracedb.ligo.org/superevents/S190426c/\n\nFor the lalinference.fits.gz skymap, the 90% credible region is 1131\ndeg2. Marginalized over the whole sky, the a posteriori luminosity\ndistance estimate is 377 +/- 100 Mpc (a posteriori mean +/- standard\ndeviation). This is the preferred sky map at this time.\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\n[1] Veitch et al.
