Abstract:
    Particularly accurate relative distances are compiled and homogenized
    for (1) 246 Type Ia supernovae and 35 clusters with v<30000km/s, and
    (2) relatively nearby galaxies with 176 tip of the red-giant branch
    and 30 Cepheid distances. The 487 objects define a tight Hubble
    diagram from 300-30000km/s implying individual distance errors of
    ≲7.5%. Here the velocities are corrected for Virgocentric steaming
    (locally 220km/s) and -if v220>3500km/s- for a 495km/s motion of the
    Local Supercluster toward the warm cosmic microwave background (CMB)
    pole at l=275, b=12; local peculiar motions are averaged out by large
    numbers.
