Prompt searches for optical signals from gravitational wavetransient candidates with Pi of the Sky

Abstract

The aim of the paper is to show methods used by Pi of the Sky team to search for optical counterparts of GW event candidates during Looc-Up science run and methods that we are planning to develop as part of the future Looc-Up. During the future joint GW-EM observations a new Pi of the Sky telescope unit could image more than 1/3 of GW candidate probability maps in less than 10 minutes, taking many pictures of the same observation field. The system could automatically recognize optical transients and perform follow-ups of interesting events.
