For injected signals recovered by both AstroPy BLS and GERBLS, the distribution of recorded S/N values from the two BLS algorithms. On average, the BLS-recorded S/N values are lower than the initial injected S/N values of those same signals by 0.05 for GERBLS and by 0.25 for AstroPy BLS, leading to an average S/N offset of 0.20 between the two shown distributions. S/N values can decrease during recovery due to the discreteness of the BLS parameter grid as well as noise in the data, but the decrease is steeper for the brute-force AstroPy BLS.
