# 7.6.1 Introduction

The short-timescale SOS work package aims to produce a list of suspected periodic short-timescale candidates with periods between a few tens of minutes to one day. This candidate list results from the analysis of Gaia time series (in $G$ CCD, $G$ FoV, $G_{\rm BP}$ and $G_{\rm RP}$), for faint sources, with sufficient number of transits in the $G$ band, and for which per-CCD time series showed a significant degree of variability at the transit level and for the majority of the transits of the source.
