Notes. The coordinates indicate the position of the X-ray peak used as the centre for profile extraction. The peak was determined using Chandra observations in the [0.7−2.5] keV band. .

^(a)

The neutral hydrogen column density was derived from the LAB survey (Kalberla et al. 2005).

^(b)

The X-ray peak is centred on the main structure, identified as region “B” in Limousin et al. (2016).

^(*)

The absorption value was estimated in a region which maximises the S/N

^(†)

MOS 2 effective exposure times are 3−4% higher than MOS1, except for MACS J1423.8+2404, for which the MOS2 exposure time is 43 ks.

^(•)

ACIS-S observations.
