... scales[*]
We make no assumption about the Gaussianity of the fields; the estimator remains unbiased even if they are not Gaussian, although optimality must be redefined in this case.

... repeated[*]
Note that we have made some changes in the two last steps compared to the description given in Melin et al. (2005). We no longer sort candidates in a tree structure for de-blending; instead, we identify and then remove candidates one by one from the filtered maps. This has only a small impact on the completeness of the detection algorithm, leaving the conclusions of our previous paper intact. The changes, however, greatly improve photometry and lower contamination.

... effects[*]
The 3-year WMAP results, published after the work presented here was finished, favor a significantly lower value of $\sigma_8$ (Spergel et al. 2006). This could lower the total number of clusters in our simulations by up to a factor of $\sim$2. As we are interested here in catalog recovery, where we compare output to input catalogs, this change should only cause relatively minor changes to our final results.

... dispersion[*]
As discussed in BM, any dispersion has only a small effect on survey sensitivity.
