Cumulative distributions of σ for BATTM orbital detections (corresponding to (o) in Figs. 5 and 6) for our 100 months of data collected with BAT. We note that 5σ detections for an average orbit correspond to 1.46 × 10^-9 erg cm^-2 s^-1 in the 15–150 keV band (8.24 × 10^-10 erg cm^-2 s^-1, 15–50 keV). We also note that the typical duration for an average orbit is 800 s for our sample.
