The Optical Gravitational Lensing Experiment. Real Time Data Analysis Systems in the OGLE-III Survey

Abstract

We describe three real time data analysis systems implemented during the third phase of the OGLE survey (OGLE-III). The EWS system is designed to detect on-going microlensing events. The EEWS system monitors the microlensing phenomena for anomalies from the single mass microlensing. The NOOS system detects transient objects in the OGLE-III fields (SNe, microlensing events, variable stars) that normally are below the detection threshold. Information on objects detected by each of these systems is distributed to the astronomical community for follow up observations. Also a short description of the OGLE-III hardware and photometric data pipeline is presented.
