The Good, the Bad and the Ugly: Statistical quality assessment of SZ detections

Understand

We examine three approaches to the problem of source classification in catalogues.

• Our goal is to determine the confidence with which the elements in these catalogues can be distinguished in populations on the basis of their spectral energy distribution (SED).
• Our analysis is based on the projection of the measurements onto a comprehensive SED model of the main signals in the considered range of frequencies.
• We first first consider likelihood analysis, which half way between supervised and unsupervised methods.
