A New Technique for Precise Stellar Photometry: Application to Small-Scale Activity of EV Lacertae
Published online by Cambridge University Press: 12 April 2016
Abstract
A new prefiltering technique (PFT) for precise stellar photometry is described. It has been proved that the prefiltered and added high-time resolution data provide an increase in S/N ratio by factors 1.3 — 1.7 in comparison with simple integration. The PFT allows to detect event amplitudes which are comparable to that caused by counting statistics. Adopting the PFT, our observations reveal small-scale flare events in the subsecond range in EV Lac.
