Scaling relations for the 17 new confirmed single-component clusters (red symbols). Black points show clusters in the Planck-ESZ sample with XMM-Newton archival data as presented in Planck Collaboration (2011g). The solid black line denotes the corresponding scaling relation fits in each panel. The blue lines in the top and bottom right panels denote the predicted Y500 scaling relations from the REXCESS X-ray observations (Arnaud et al. 2010). The blue line in the bottom left panel is the Malmquist bias corrected M–L relation from the REXCESS sample (Pratt et al. 2009; Arnaud et al. 2010). In all figures, R500 and M500 are estimated from the M500–YX relation of Arnaud et al. (2010). Top row: relation between apparent SZ signal (Y500, left) or intrinsic Compton parameter (, right) and the corresponding normalised YX parameter. Bottom row: relation between X-ray luminosity and Y500 (left) and between mass and luminosity (right panel). The new clusters are on average less luminous at a given Y500, or more massive at a given luminosity, than X-ray selected clusters.
