Significance levels of common frequencies extracted from multiple data sets
(Oxford University Press, 2020)
Large monitoring campaigns, particularly those using multiple filters, have produced replicated time series of observations for literally millions of stars. The search for periodicities in such replicated data can be ...
Correcting CCD photometry of stars for seeing effects
(Oxford Univeristy Press, 2009)
Systematic variability in stellarmagnitudes, as derived from profile fitting to CCD images,may
in some instances be due to variable seeing. It is suggested that this happens in cases where the
stars are unresolved pairs, ...
The analysis of indexed astronomical time series – X. Significance testing of O − C data
(Oxford University Press, 2006)
It is assumed that O − C (‘observed minus calculated’) values of periodic variable stars are
determined by three processes, namely measurement errors, random cycle-to-cycle jitter in
the period, and possibly long-term ...
The analysis of irregularly observed stochastic astronomical time-series – I. Basics of linear stochastic differential equations
(Oxford University Press, 2005)
The theory of low-order linear stochastic differential equations is reviewed. Solutions to these
equations give the continuous time analogues of discrete time autoregressive time-series. Explicit
forms for the power ...
