This module provides utilities for calculating detector responses. This was grabbed from https://github.com/gwastro/pycbc/blob/master/pycbc/detector.py

class xpipeline.core.xdetector.Detector(detector_name)

Bases: object

A gravitaional wave detector

compute_antenna_response(self, phi, theta, psi=0)

Return the detector response.

light_travel_time_to_detector(self, det)

Return the light travel time from this detector Parameters ———- detector: Detector

The other detector to determine the light travel time to.

time: float

The light travel time in seconds

optimal_orientation(self, t_gps)

Return the optimal orientation in right ascension and declination for a given GPS time.

project_wave(self, hp, hc, longitude, latitude, polarization)

Return the strain of a wave with given amplitudes and angles as measured by the detector.

time_delay_from_detector(self, other_detector, right_ascension, declination, t_gps)

Return the time delay from the given to detector for a signal with the given sky location; i.e. return t1 - t2 where t1 is the arrival time in this detector and t2 is the arrival time in the other detector. Note that this would return the same value as time_delay_from_earth_center if other_detector was geocentric.

Parameters

other_detector : detector.Detector

A detector instance.

right_ascension : float

The right ascension (in rad) of the signal.

declination : float

The declination (in rad) of the signal.

t_gps : float

The GPS time (in s) of the signal.

Returns

float :

The arrival time difference between the detectors.

time_delay_from_earth_center(self, right_ascension, declination, t_gps)

Return the time delay from the earth center

time_delay_from_earth_center_phi_theta(self, phi, theta)

Return the time delay from the earth center

xpipeline.core.xdetector.effective_distance(distance, inclination, f_plus, f_cross)

xpipeline.core.xdetector.compute_antenna_patterns(detectors, phi, theta, **kwargs)

Compute the antenna patterns for a set of detectors and a sky location

Parameters

detectors : list

A list of detector by there abbr i.e. H1, L1 etc.

phifloat

Earth fixed coordinate of signal

thetafloat

The earth fixed coordinate of signal.

antenna_patternslist

list of antenna patterns to calculate and return

Returns

dict :

key-wise dict were keys are antenna pattern name values are XFrequencyDicts
