Orbital intensity profile of IGR J16318−4848 obtained by folding the Swift/BAT daily light curves with a period of 80.09 days (±0.012) and a reference epoch of MJD 53477.577, adopted from N. Iyer & B. Paul (2017). The reference epoch is chosen such that the peak BAT flux occurs at an orbital phase of ϕorb = 0.5. The orbital phases of the Chandra ObsIDs closest to the BAT data points (within a phase difference <0.007) are listed on the right.
