A1068 cold fronts analysis. Upper left panel: X-ray Chandra image with indicated the positions of cold fronts: red arc for the NW outer CF, black arc for the NW inner CF and green arc for the SE CF. Upper right panel: best-fitting broken power-law model (blue line) with associated residuals of the SB discontinuity in the south-east profile. The red line indicates the position of the putative PDL. Middle left panel: same as before for the inner SB discontinuity in the north-west profile. Middle right panel: same as before for the outer SB discontinuity in the north-west profile. Lower panels: Temperature profiles across the north-west (black), south-west (red), south-east (blue) and north-east (green) sectors. The dashed grey lines indicate the position of cold fronts.
