Abstract

Two fully automatic Pi of the Sky detectors with a large field of view, located in Spain (INTA) and in Chile (SPDA) observe the sky in search of rare optical phenomena, and also collect observations which include many kinds of variable stars. To be able to draw proper conclusions from the data that is received, adequate quality of the detectors is very important. Pi of the Sky data are subject to systematic errors caused by various factors, e.g. cloud cover seen as significant fluctuations in the number of stars observed by the detector, problems with conducting mounting, a strong background of the moon or the passage of a bright object, e.g. a planet, near the observed star. Some of these adverse effects are already detected during cataloging of the individual measurements, but this is not sufficient to make the quality of the data satisfactory for us. In order to improve the quality of our data, we developed two new procedures based on two different approaches. In this paper we will say some words about these procedures, give some examples, and show how these procedures improve the quality of our data.
