Scientific paper

The topic of the paper is a preliminary analysis of 1743 data calculated for 249 High-z SCP Union supernovae, according to the expansion center model. The analysis of the ECM data set in Hubble units begins with 13 listed normal points corresponding to 13 z-bin samples at as many Hubble depths. Here the novel finding is a resulting clear drop in the average scattering of the SNe Ia Hubble Magnitudes M with the ECM Hubble depth D, after using the average trend computed in paper IX and here reconfirmed. Other correlations of the M scattering with the position in the sky are proposed as pointers for future investigations. Consequently, 13 ECM dipole tests on the 13 z-bin samples were carried out both with unweighed and weighed fittings. A further check was made through another ECM dipole test on the same 13 z bins, with Hubble depths D obtained by assuming M= according to paper IX and X. In conclusion the analysis of 249 SCP SNe confirms once again the expansion center model at any Hubble depth, including a strengthening perturbation effect of the M scattering at decreasing z<0.5. The present version includes the ADDENDUM NOTE - October 2011 - "Quick test of DL=r(1+z)(1+z) on High-z SCPU supernovae: reconfirming the ECM decelerated Universe even with =-18.01".
