Prediction of the yearly rate of mergers as a function of the total source-frame mass of the binary. Thick lines show the median and shaded areas the 90% confidence region after fitting for the LF and the GW background of EPTA. The green curves correspond to the intrinsic merger rate, while the light green curves show the rate of events detectable by LISA, assuming an S/N threshold of 10. Predictions from other models are included for comparison.
