The most obvious effect is a distortion of the white noise level in the power density spectrum (PDS) that cannot be modeled easily with the standard techniques due to the variable nature of the dead time.

Flexible and Scalable Methods for Quantifying Stochastic Variability in the Era of Massive Time-Domain Astronomical Data Sets

2 code implementations • 24 Feb 2014 • Brandon C. Kelly, Andrew C. Becker, Malgosia Sobolewska, Aneta Siemiginowska, Phil Uttley

We present the use of continuous-time autoregressive moving average (CARMA) models as a method for estimating the variability features of a light curve, and in particular its power spectral density (PSD).
