Tolman SB test for a non-expanding Euclidean Universe as derived from Lubin and Sandage 4 data, restricted to the region of overlap in luminosity between local and distant samples. Surface brightness in VEGA mag/arcsec 2 is k-corrected and made brighter by a factor 2.5Log(1+z) to remove the expected dimming. Thus, in absence of expansion, galaxies of the same luminosity should have the same SB within the scatter of the SB - luminosity relation. They should also have comparable physical radius.The transformation from arcsec to pc was done assuming d=cz/H0 for all redshifts. Different symbols refers to the local sample at z=0.037 (Dots), galaxies in cluster Cl 1604 + 43 atz=0.924 (squares), cluster Cl 1604+43 atz=0.897 (Diamonds), and cluster Cl 1324+30z=0.756 (Triangles)
