Based on a null-correlation approach (NCA), the technique is insensitive to the presence of selection effects on apparent magnitude $m$ and on log line-width distance indicator $p$. This interesting property is used for discarding near by galaxies of the observed sample. It is shown that such a subsampling allows in effect to attenuate biases on calibration parameters created by the presence of radial peculiar velocities.20 pages, 24 figures.
