The different types of +offsets are listed below: + +Overall phase offset +'''''''''''''''''''' +The pulse phase corresponding to the TOAs are usually computed in reference to an arbitrary +fiducial TOA known as the TZR TOA (see :class:`pint.models.absolute_phase.AbsPhase`). Since the +choice of the TZR TOA is arbitrary, there can be an overall phase offset between the TZR TOA and +the measured TOAs. There are three ways to account for this offset: (1) subtract the weighted mean +from the timing residuals, (2) make the TZR TOA (given by the `TZRMJD` parameter) fittable, or +(3) introduce a fittable phase offset parameter between measured TOAs and the TZR TOA. +Traditionally, pulsar timing packages have opted to implicitly subtract the residual mean, and this +is the default behavior of `PINT`. Option (2) is hard to implement because the TZR TOA may be +specified at any observatory, and computing the TZR phase requires the application of the clock +corrections. The explicit phase offset (option 3) can be invoked by adding the `PHOFF` parameter, +(implemented in :class:`pint.models.phase_offset.PhaseOffset`). If the explicit offset `PHOFF` +is given, the implicit residual mean subtraction behavior will be disabled. + +System-dependent delays +''''''''''''''''''''''' +It is very common to have TOAs for the same pulsar obtained using different observatories, +telescope receivers, backend systems, and data processing pipelines, especially in long-running +campaigns. Delays can arise between the TOAs measured using such different systems due to, among +other reasons, instrumental delays, differences in algorithms used for RFI mitigation, folding, TOA +measurement etc., and the choice of different template profiles used for TOA measurement. Such +offsets are usually modeled using phase jumps (the `JUMP` parameter, see :class:`pint.models.jump.PhaseJump`) +between TOAs generated from different systems. + +System-dependent DM offsets +''''''''''''''''''''''''''' +Similar to system-dependent offsets, offsets can arise between wideband DM values measured using +different systems due to the choice of template portraits with different fiducial DMs. This is +usually modeled using DM jumps (the `DMJUMP` parameter, see :class:`pint.models.dispersion_model.DispersionJump`). + Observatories ------------- -PINT comes with a number of defined observatories.
