Eyer & Bartholdi showed that the Nyquist frequency of irregularly sampled time‐series can be very high. In this paper, a calculation formula for the Nyquist frequency is presented. In practice there is an upper limit of 0.5/Δ on this frequency, where Δ is the best accuracy with which time is recorded.
