This tutorial highlights some advanced Peranso features. We will learn to analyse the periodicities in a large set of observations of the Delta Scuti star V350 Peg1. We will ‘re-discover’ the multi-periodicities of this variable star using the technique of prewhitening. We conclude the tutorial by an advanced analysis of the statistical significance (False Alarm Probability) of the identified periods, and of their uncertainty (Period Error).
