Extended Data Fig. 3: Corner plot showing posterior distributions for the basic kilonova model.
From: A kilonova following a long-duration gamma-ray burst at 350 Mpc
This model consists of three ejecta components and a fraction ζ of the blue (low-lanthanide) ejecta that is heated by shocks from the GRB jet. The final parameter is a white-noise term for modelling systematics in the data. The labelled 1σ error bars are statistical only; we estimate further systematic error of about 50% on these parameters (see Methods).
