Introduction

The PF DET-CL is being implemented with two different cluster detection codes: AMICO and PZwav. Their algorithms are different, but each of them satisfies the PF requirements.

The input files are the galaxy catalog including the photometric redshift, the mask applied on these catalogs and a parameter file providing the information needed by both AMICO and PZWav. In addition, AMICO requires a specific model file, which is a set of static parameters vectors describing the cluster model.

A first output is the list of detected clusters and their characteristics. This data product has unified columns for both detection codes, one of the columns, the SNR one, has a different meaning when computed by AMICO or PZWav. The second output Data Products according to the RSD is the catalog of the galaxy membership of the clusters; it is currently only provided by AMICO code.

In addition, we propose a number of intermediate data product outputs for each one of these codes. These do not appear in the PF requirements but are estimated to be valuable for checking and/or for re-computing the PF output. The need for keeping these files as Data Products can in any case be discussed and re-assessed in the future. The detection code which generates each of them appears explicitely in their name (ex : detclPZWAVDensityMap).

This is summarized in the flowchart of the intermediate data products:
