bilby.gw.utils.get_vertex_position_geocentric
- bilby.gw.utils.get_vertex_position_geocentric(latitude, longitude, elevation)[source]
Calculate the position of the IFO vertex in geocentric coordinates in meters.
Based on arXiv:gr-qc/0008066 Eqs. B11-B13 except for the typo in the definition of the local radius. See Section 2.1 of LIGO-T980044-10 for the correct expression
- Parameters:
- latitude: float
Latitude in radians
- longitude:
Longitude in radians
- elevation:
Elevation in meters
- Returns:
- array_like: A 3D representation of the geocentric vertex position
