Posterior of the joint KN+GRB afterglow analyses of GRB211211A. Selected parameters are shown in the corner plot. The full corner plot can be accessed in our data repository. The lightblue contours indicate the posterior when the GRB afterglow part is fit with AFTERGLOWPY, magenta is the posterior from PYBLASTAFTERGLOW. Both inferences use the KN surrogate from POSSIS. The lightgrey contours show the analysis from Kunert et al. (2024) as a reference.
