We compare the density fields from POTENT and IRAS. We vary the smoothing scale, and use a non-parametric test to obtain a value for the linear bias parameter b, as a function of offset c, which arises because the normalisation volumes for the two samples are different (Dekel et al., 1993). The smoothed fractional overdensities are related by δP = δI/b + c.
