IXPE photon (upper panel) and EF_E spectra (lower panel) of XTE J1701−462 during Obs. 1, along with the best-fit model (see Table 1) consisting of diskbb for the accretion disk (blue dotted curve) and bbodyrad for the BL-SL layer (red dashed) as well as their sum (black solid). The residuals are shown in the middle panel. Blue, red, and green color correspond to DUs 1–3, respectively.
