Detailed Description

This structure contains the required information for generating a ringdown injection.

The fields are:

waveform: Description of the type of waveform to inject.
coordinates: Type of coordinate system to perform injection.
geocent_start_time: The GPS start time of the waveform at the center of the earth.
h_start_time: The GPS start time of the waveform at the LIGO Hanford Observatory.
l_start_time: The GPS start time of the waveform at the LIGO Livingston Observatory.
v_start_time: The GPS start time of the waveform at the Virgo Observatory.
start_time_gmst: The start time of the waveform at the in siderial time.
longitude: The longitude of the source defined in the stated coordinate system.
latitude: The latitude of the source defined in the stated coordinate system.
distance: The distance to the source defined in the stated coordinate system in megaparsecs (Mpc).
inclination: The inclination angle \(\iota\) of the source.
polarization: The polarization angle \(\Psi\) of the source.
frequency: The central frequency of the ringdown waveform (in Hz).
quality: The quality factor \(Q\) of the ringdown waveform.
phase: The initial phase of the ringdown signal \(\phi_0\).
mass: The mass \(M\) of the black hole (in solar masses, \(M_\odot\)).
spin: The dimensionless spin parameter of the black hole \({\hat{a}}\) where the spin is \(S={\hat{a}}GM^2/c\) ( \(G\) is Newton constant and \(c\) is the speed of light).
epsilon: The fractional mass loss \(\epsilon\) of the initial black hole mass in ringdown radiation.
amplitude: The peak strain amplitude \(h_0\) of the waveform, given by
\begin{equation} h_0=\sqrt{\frac{5}{2}\epsilon}\left(\frac{GM}{c^2 r}\right) Q^{-\frac{1}{2}} F(Q)^{-\frac{1}{2}} g(a)^{-\frac{1}{2}}, \end{equation}
where \(F(Q) = 1 + 7/(24 Q^2)\), \(g(a) = 1 - 0.63(1-a)^{3/10}\) and \(r\) is the distance to the trigger.
h_eff_dist: The effective distance to the source from the LIGO Hanford Observatory in megaparsecs (Mpc).
l_eff_dist: The effective distance to the source from the LIGO Livingston Observatory in megaparsecs (Mpc).
v_eff_dist: The effective distance to the source from the Virgo Observatory in megaparsecs (Mpc).
hrss: Define.
hrss_h: Define.
hrss_l: Define.
hrss_v: Define.
