The ZTF Source Classification Project: II. Periodicity and variability processing metrics

Understand

The current generation of all-sky surveys is rapidly expanding our ability to study variable and transient sources.

• These surveys, with a variety of sensitivities, cadences, and fields of view, probe many ranges of timescale and magnitude.
• Data from the Zwicky Transient Facility (ZTF) yields an opportunity to find variables on timescales from minutes to months.
• In this paper, we present the codebase, ztfperiodic, and the computational metrics employed for the catalogue based on ZTF's Second Data Release.
