Multicolour light curves in X-ray, UV (uvm2), optical (BRI) and infrared (K) are compared to models’ predictions of a kilonova (solid line) in addition to the non-thermal emission (dashed line). The shaded area shows the range of possible fluxes reproduced by kilonova simulations with wind mass Mw between 0.01M☉ (lower bound) and 0.1M☉ (upper bound), and dynamical ejecta mass Md between 0.01M☉ (lower bound) and 0.03M☉ (upper bound). Error bars represent 1σ; upper limits (downward triangles) are 3σ. For plotting purposes, light curves were shifted by a constant factor, as indicated by the numbers in the legend.
