Table A.1.

Best-fit β-model parameters for RXCJ1825 and CIZAJ1824 clusters.

Cluster RA Dec (J2000) β rc S0 const χ2 d.o.f.
RXCJ1825 18:25:21.77, +30:26:25.3 0.562 ± 0.008 3.08 ± 0.06 0.0146 ± 0.0002 1.9 ± 0.1 318.4 140
CIZAJ1824 18:24:07.11, +30:29:34.7 0.445 ± 0.003 0.18 ± 0.01 0.2082 ± 0.0078 1.5 ± 0.2 126.5 56

Notes. Columns are: cluster name, X-ray centroid coordinates in degrees [J2000], beta parameter, core radius in arcmin, central surface brightness in cts s−1 arcmin−2, constant sky background in units of 10−4 cts s−1 arcmin−2, chi-square and degrees of freedom. Neither RXCJ1825 nor CIZAJ1824 show a significant best-fit improvement with a double-β model, as evident from the F-test.
