XRTDC (2−10 kev) as a function of orbital period and for a range of 2−10 keV luminosities (see legend, in units of erg s^-1) in black. All values are also reported for J08408 and J1841, which lack an orbital period measurement, as blue data points at an arbitrary orbital period shorter than two days. Only points above 0.1% are shown. The shaded areas mark the loci of XRTDC defined with contiguous luminosities. The red filled stars represent the XRT DC at the INTEGRAL sensitivity for each object (the downward-pointing arrows are consistent with 0).
