GCN Circular 21489
The LIGO Scientific Collaboration and the Virgo Collaboration report: In GCN 21474, we reported the identification of the GW binary merger candidate G297595. The originally stated luminosity distance estimate of 550 +/- 130 Mpc (a posteriori mean +/- standard deviation) was incorrect due to copying the value from a different GraceDB entry. The correct luminosity distance estimate is 488 +/- 111 Mpc. The original sky map that we sent in GCN 21474, bayestar.fits.gz, contains the correct value in the DISTMEAN and DISTSTD entries of its FITS header. Only the circular was in error. No further updates are available at this time.
