Summary:The optimal arrival time estimators for single and multiple
photons arriving at the surface of a photomultiplier tube (PMT) are
developed. The optimal timing estimator considered is a weighted
nonlinear least squares estimate of the detection time for a high-gain
PMT with Gaussian statistics. The least squares estimator is constructed
using the mean and covariance function of the photomultiplier output for
different arrival times. The root-mean-square error for the least
squares arrival time estimator was calculated and is compared with the
performance of other common timing estimators, including the first
photoelectron timing estimators, using a Burle/RCA 8850 PMT
