wcosmo.wcosmo.detector_to_source_frame#
- wcosmo.wcosmo.detector_to_source_frame(m1z, m2z, dL, H0, Om0, w0=-1, method='pade', zmin=0.0001, zmax=100)[source]#
Convert masses and luminosity distance from the detector frame to source frame masses and redshift.
This passes through the arguments to z_at_value to compute the redshift.
- Parameters:
- m1z: array_like
The primary mass in the detector frame
- m2z: array_like
The secondary mass in the detector frame
- dL: array_like
The luminosity distance in Mpc
- H0: array_like
The Hubble constant in km/s/Mpc
- Om0: array_like
The matter density fraction
- w0: array_like
The (constant) equation of state parameter for dark energy
- zmin: float
The minimum redshift used in the conversion from distance to redshift, default=1e-4
- zmax: float
The maximum redshift used in the conversion from distance to redshift, default=100
- Returns:
- m1, m2, z: array_like
The primary and secondary masses in the source frame and the redshift
