CCDs of each source using the IXPE observations (Table 1). The soft and hard colors are defined as the ratio of the counts in the 3–5 keV/2–3 keV and 5–8 keV/3–5 keV bands, respectively. Different colors correspond to different observation of the source. Each bin corresponds to 1000 s. (a) Cyg X-2. (b) XTE J1701–462. (c) GX 5–1. (d) Sco X-1. (e) GX 340+0. (f) GX 349+2.
