Extended Data Fig. 4: Potential constraints on kilonova model parameters based on the deepest limiting magnitudes.
From: Optical follow-up of the neutron star–black hole mergers S200105ae and S200115j

We display constraints on a, S200105ae (ZTF), b, S200115j (ZTF) and c, S190814bv (DECam) for the models in the NSBH grid used here. Top panels: same as Figure 4 but using the deepest (filled triangles) rather than the median limits for each set of S200105ae and S200115j observations. The panel for S190814bv is the same as in Figure 4, with all limits corresponding to the median magnitudes. Bottom panels: regions of the Mej,dyn − Mej,pm parameter space that are ruled out at different distances and for different viewing angle ranges (moving from pole to equator from top to bottom panel).
