Earth detectors

class gwtoolbox.detectors_earth.LigoLike(det)

This class describes LIGO-like detectors

Parameters:det (int) – detector ID (0 - Virgo, 1 - LIGO, -1 - LIGO-like)

ante_pattern(theta, varphi, psi)

The Antenna Pattern of LIGO-like (two arms with 90 deg) Gravitational Waves (GW) Observatories.

Parameters:

• theta (float) – the polar angle of the GW source in the detector coordinates frame
• varphi (float) – the azimuth angle of the GW source in the detector coordiantes frame
• psi (float) – the polarization angle of the GW

Returns:

size=2, [Fplus, Fcross]

Return type:

(array of dtype float)

noise_curve(pars=None)

The Noise power spectrum of LIGO-like GW observatories.

Parameters:pars (Optional[list of floats]) – which defines the configuration of the LIGO-like detector, this list of parameters will be passed to FINESSE Returns:noise vs. frequency, size=(,2), the 0-th column are frequencies, and 1-st column are corresponding noise power Return type:(array of dtype float)

class gwtoolbox.detectors_earth.ETLike(det)

This class describes ET-like detectors

Parameters:det (int) – detector ID (2 - ET, -2 - ET-like)

ante_pattern(theta, varphi, psi, Nnest=3)

The Antenna Pattern of ET-like (multiple detectors nested, each has two arms with 60 deg) Gravitational Waves (GW) Observatories.

Parameters:

• theta (float) – the polar angle of the GW source in the detector coordinates frame
• varphi (float) – the azimuth angle of the GW source in the detector coordiantes frame
• psi (float) – the polarization angle of the GW
• Nnest (int) – The number of nested detectors

Returns:

size=(Nnext,2). The i-th row are the Antenna Patterns [Fplus,Fcross] of the i-th nested detector

Return type:

(array of dtype float)

noise_curve(pars=None)

The Noise power spectrum of ET-like GW observatories.

Parameters:pars (Optional[list of floats]) – define the configuration of the ET-like detector, this list of parameters will be passed to FINESSE ??? Returns:noise vs. frequency, size=(,2), the 0-th column are frequencies, and 1-st column are corresponding noise power Return type:(array of dtype float)
