cogwheel.gw_prior.extrinsic.ReferenceDetectorMixin

class cogwheel.gw_prior.extrinsic.ReferenceDetectorMixin

Bases: object

Methods for priors that need to know about the reference detector. They must have tgps, ref_det_name attributes.

Methods

fplus_fcross_refdet	Antenna coefficients (F+, Fx) at the reference detector.
geometric_factor_refdet	Return the complex geometric factor
time_delay_refdet	Time delay from Earth center to the reference detector.

Attributes

ref_det_location

3d location of the reference detector on Earth [meters].

fplus_fcross_refdet(ra, dec, psi)

Antenna coefficients (F+, Fx) at the reference detector.

geometric_factor_refdet(ra, dec, psi, iota)

Return the complex geometric factor

\[R = \frac{1+\cos^2 \iota}{2} F_{+} - i \cos \iota \ F_{\times}\]

that relates a waveform with generic orientation to an overhead face-on one for quadrupolar waveforms. Note that the amplitude |R| is between 0 and 1.

property ref_det_location

3d location of the reference detector on Earth [meters].

time_delay_refdet(ra, dec)

Time delay from Earth center to the reference detector.
