CONAN._classes.load_lightcurves.transit_timing_variation(ttvs='n', dt=(-0.125, 0, 0.125), baseline_amount=0.25, per_LC_T0=False, include_partial=True, show_plot=False, print_linear_eph=True, verbose=True)#

include transit timing variation between the transit. Note: Reference ‘T_0’ and ‘P’ values are fixed to the start values defined in .planet_parameters(). The transit times expected for each transit of a planet is calculated automatically

Parameters:

  • ttvs (str ("y" or "n");) – specify if to fit transit timing variation or not. default is “n”

  • dt (tuple of len 2 or 3;) – deviation of transit times from the expected values. Must be tuple of len 2/3 specifying (mu,std)/(min,start,max). this deviation is added to the expected linear ephemeris time, where n is the transit number. Default is 180mins around expected T0 i.e (-0.125,0,0.125) e.g. T0_linear = 1406, dt=(-0.125,0,0.125) –> T0_prior = U(1406-0.125, 1406, 1406+0.125) dt = (0,0.125) –> T0_prior = N(1406, 0.125)

  • baseline_amount (float;) – amount of baseline around each transit to use in extracting the transit. Default is 0.25 times the planet period. Only used to split transits when per_LC_T0=False.

  • per_LC_T0 (bool;) – whether to fit a single T0 per LC file as opposed to a T0 per transit.

  • include_partial (bool;) – include partial transits in the TTV analysis. Default is False.

  • show_plot (bool;) – show plot of the extracted transits. Default is False.

  • print_linear_eph (bool;) – print linear ephemeris. Default is False.
