bilby.gw.utils.calculate_time_to_merger
- bilby.gw.utils.calculate_time_to_merger(frequency, mass_1, mass_2, chi=0, safety=1.1)[source]
Leading-order calculation of the time to merger from frequency
This uses the XLALSimInspiralTaylorF2ReducedSpinChirpTime routine to estimate the time to merger. Based on the implementation in pycbc.pnutils._get_imr_duration.
- Parameters:
- frequency: float
The frequency (Hz) of the signal from which to calculate the time to merger
- mass_1, mass_2: float
The detector frame component masses
- chi: float
Dimensionless aligned-spin param
- safety:
Multiplicitive safety factor
- Returns:
- time_to_merger: float
The time to merger from frequency in seconds
