# Errata and Enhancements

- 19-Jan-00 We were alerted to a typo. in equation (3.3) of the
Journal paper MNRAS 300,945

The Power Law bias model (model 5) that we used assumes

** Probability proportional to (density)^alpha **

and ** NOT ** as erroneously stated

** Probability proportional to (nu)^alpha **

where

nu = rho/sigma - 1 .
- On 3-June-98 minor revisions were made to the text of the paper
in response to a helpful referee's report.
- On 29-May-98 we included the
** unbiased ** mass distributions
sampled according to the various survey boundaries and
selection functions for the subset of cosmological models
to which we applied each of the 6 biasing algorithms.
These new mock catalogues of just the mass distribution
are not of direct use for people analysing the observational
catalogues, but may be of use to people studying the effect
of bias in the various cosmological models. Note that as
they are unbiased the mass correlation functions will generally be
very different to the observed galaxy correlation function.
- The following catalogues were replaced on 31-Jan-98
as the previous versions had their "zhmax" values set
incorrectly.
