class pint.models.stand_alone_psr_binaries.binary_orbits.OrbitWaves(parent, orbit_params=['PB', 'TASC', 'ORBWAVE_OM', 'ORBWAVE_EPOCH', 'ORBWAVEC0', 'ORBWAVES0'])[source]

Bases: Orbit

Orbit with orbital phase variations described by a Fourier series.

Methods

`d_orbits_d_PB`()
`d_orbits_d_TASC`()
`d_orbits_d_orbwave`(par)
`d_orbits_d_par`(par)	Derivative of orbital phase with respect to some parameter.
`d_pbprime_d_PB`()
`d_pbprime_d_orbwave`(par)
`d_pbprime_d_par`(par)	Derivative of binary period with respect to some parameter.
`orbit_phase`()	Orbital phase (between zero and two pi).
`orbits`()	Orbital phase (number of orbits since TASC).
`pbdot_orbit`()	Reported value of PBDOT.
`pbprime`()	Instantaneous binary period as a function of time.

orbits()[source]: Orbital phase (number of orbits since TASC).

pbprime()[source]: Instantaneous binary period as a function of time.

pbdot_orbit()[source]: Reported value of PBDOT.

d_orbits_d_par(par)[source]: Derivative of orbital phase with respect to some parameter.

Note

This gives the derivative of orbit_phase, that is, it is scaled by 2 pi with respect to the derivative of orbits.

d_pbprime_d_par(par)[source]: Derivative of binary period with respect to some parameter.

orbit_phase(): Orbital phase (between zero and two pi).
