Absorbed dual black body spectral fits of OGLE16aaa during (a) the Spring 2016 optical/UV peak, (b) June 9, 2016 XMM-Newton observation, (c) during the stacked June 16–21 Swift/XRT observation and (d) the November 30, 2016 XMM-Newton observation. The OGLE I and V filter data are shown with purple and green points, the Swift/UVOT uvw1, uvm2, and uvw2 data with cyan, pink, and blue, the XMM-Newton/PN and Swift/XRT data are shown in red, while XMM-Newton/MOS1 and MOS2 are shown in black and brown, respectively. The unabsorbed, and de-reddened black bodies corrected for Milky Way absorption are shown with dotted and dashed lines, while the unabsorbed DISKBB component is shown with a dot-dashed lines. We note the large positive residuals in panel d, indicating a presence of a weak, but significant, high-energy X-ray tail.
