bilby.gw.geometry.time_delay_from_geocenter

bilby.gw.geometry.time_delay_from_geocenter(detector1, ra, dec, time)

Calculate time delay from geocenter to a detector.

Parameters:

detector1: array-like: 3D position vector of the detector in meters.
ra: float or array-like: Right ascension of the source in radians.
dec: float or array-like: Declination of the source in radians.
time: float or array-like: GPS time of the observation.

Returns:

float or array-like: Time delay \(\Delta t = \hat{\omega} \cdot \vec{d} / c\) in seconds, where \(\vec{d}\) is the detector position and \(c\) is the speed of light.
