Pi of the Sky involvement in LSC-Virgo Electromagnetic Follow-up project

Pi of the Sky took a part in LSC-Virgo’s Electromagnetic (EM) Follow-up project during first science run of Advanced LIGO detectors between September 2015 and January 2016. More than 60 astronomical teams have signed Memorandum-of-Understanding with LSC-Virgo for EM Follow-up project. LSC-Virgo’s EM Follow-up is aimed for searching electromagnetic counterparts to gravitational wave transient candidates. Finding such a transient to gravitational wave might be a important step forward to multi-messenger astronomy by observing an event both in EM and gravitational wave band. The aim of this paper is to show algorithms used by Pi of the Sky for analysing data taken during the science runs.
