• Deprojection/deconvolution of profile from Planck SZ map
⇒ 0.02-5 R500 from X-ray+SZ
⇒ X-ray and SZ view consistent , No ‘missing’ hot baryons ⇒ Low dispersion ⇒ Shallower than expected by simulations at high radius
47th ESLAB conference 2/04/13 SZ-X scaling relation
• Ratio consistent with X-ray P shape
• Error now dominated by systematics ⇒ limit clumpiness constrain
• Low scatter relation ⇔ Y /Y good mass prox YX = MgasTX SZ X
