orbits()	Orbital phase (number of orbits since TASC).
pbdot_orbit()	Reported value of PBDOT.

orbits()

Orbital phase (number of orbits since TASC).

pbprime()

Instantaneous binary period as a function of time.

pbdot_orbit()

Reported value of PBDOT.

d_orbits_d_par(par)

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)

Derivative of binary period with respect to some parameter.

orbit_phase()

Orbital phase (between zero and two pi).
