S/N determined with the standard implementation in PSRCHIVE as a function of simulated S/N. The blue points are the S/N of the individual simulations, and the red points indicate the median value of the simulations. The red error bars indicate the 25th and 75th percentiles at each real S/N. For this simulation, the analytic template based on NRT data of PSR J2145−0750 was used. Due to differences in the definition of the S/N, some inconsistencies between x and y values are expected, although the scaling should be linear, as is the case in the high-S/N regime. In the low S/N regime (S/N < 10), the S/Ns returned by PSRCHIVE are typically overestimated and have a significant random component. (The thick black lines indicate S/Ns of 8, which is used as an S/N cut-off value in this work, following Arzoumanian et al. 2015).
