Abstract

For pulsar projects it is often necessary to predict the pulse phase inadvance, for example when preparing for new observations. Interpolationof the pulse phase between existing measurements is also often required,for example when folding X-ray or gamma-ray observations according tothe radio pulse phase. Until now these procedures have been done usingvarious ad hoc methods. The purpose of this paper is to show how tointerpolate or predict the pulse phase optimally using statisticalmodels of the various noise processes and the phase measurementuncertainty.
