X-ray analysis of PSZ1G139.61+24. Upper left panel:Chandra 0.5–7.0 keV image, with represented a portion of the extraction regions. The black arc indicates the cold front position. Upper central panel: GGM filtered image. Upper right panel: Residual image after the subtraction of a double β-model. Lower left panel: SB profiles extracted along the directions depicted in the upper left panel. Lower central panel: best-fitting double β-model (blue line) with associated residuals of the SE profile. Lower right panel: best-fitting broken power-law model (blue line) with associated residuals on the SB discontinuity in the NW profile.
