Query: Detection of extensive air showers with the NEVOD-EAS cluster type
  detector   A new cluster type shower array NEVOD-EAS is designed for estimating the
size, axis position and arrival direction of extensive air showers registered
by the Cherenkov water detector NEVOD and coordinate detector DECOR (Moscow,
Russia). In 2015-2016, the central part of the array was deployed and started
its operation. It includes 4 independent clusters of scintillation detector
stations located around the NEVOD-DECOR experimental complex on the area of
about $10^{4} m^{2}$. This article presents the results of studying amplitude
and timing characteristics of the array clusters which are critical for EAS
parameters reconstruction, as well as the examples of registered events.
