Constraints on the ejecta masses and viewing angle, with other parameters (vej, Ye) fixed to the best-fit values of AT 2017gfo. The color scale indicates the grid excluded fraction of the parameter space. Red stars mark the inferred ejecta masses and viewing angle for AT 2017gfo, shown for comparison.
