Galaxy clusters with PzWav on S-PLUS DR1

These groups and clusters are distributed over 273 deg^2^ in the Stripe 82 region. They are found using the PzWav algorithm, which identifies peaks in galaxy density maps that have been smoothed by a cluster scale difference-of-Gaussians kernel to isolate clusters and groups.

Using a simulation-based mock catalogue, we estimate the purity and completeness of cluster detections: at S/N > 3.3, we define a catalogue that is 80 per cent pure and complete in the redshift range 0.1 < z < 0.4, for clusters with M_200_ > 10^14^ M_{Sun}_. We also assessed the accuracy of the catalogue in terms of central positions and redshifts, finding scatter of {sigma}_R_ = 12 kpc and {sigma}_z_ = 8.8
