Notes. Flux and luminosity errors
include the Poisson errors and a 5% systematic error in the background estimation.
Errors of parameters obtained from scaling relations include
the measurement errors of the luminosity and temperature, respectively, and the
intrinsic scatter of the scaling relations. We assume self-similar evolution
for all the scaling relations and no evolution of their intrinsic scatters (see
Sect. 2.2.1).
(a) X-ray coordinates based on a maximum-likelihood fit of a PSF-folded
beta model to the surface brightness distribution; (b) High et al. (2010); (c) spectroscopic temperature (Sect. 2.2.1), error bars averaged, assuming isothermality; (d) M-T relation from Arnaud et al. (2005), using relations for T >3.5 keV,
self-similar evolution, radii calculated analytically from the mass estimates; (e)
relation (Arnaud et al. 2007). (f) L-T relation from Pratt et al. (2009), self-similar evolution, relation for the 0.5-2 keV
luminosity, BCES orthogonal fit; (g)
relation from Pratt et al. (2009), self-similar evolution,
relation for the 0.5-2 keV luminosity, BCES orthogonal fit. YX, the X-ray analogue
to the Comptonization parameter Y, is the product of the gas mass and temperature
(e.g. Kravtsov et al. 2006).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
