Detailed Description

Functions that predict pulse phase.

This simple version assumes folding at a fixed topocentric frequency, as e.g. a pulsed cal.

Member Function Documentation

insert()

virtual void Pulsar::FixedFrequencyPredictor::insert ( const Predictor *  )

inlinevirtual

Add the information from the supplied predictor to self.

This method should check to avoid inconsistency and duplication
