Explanation
The likelihood of a strong lensing time-delay system as
modelled in http://arxiv.org/pdf/1306.4732v2.pdf
and http://arxiv.org/pdf/0910.2773v2.pdf
##Parameters
These parameters can be set in the module's section in the ini parameter file.
If no default is specified then the parameter is required.
| Parameter | Description |
|---|---|
| lens_name | String, default='None'; name of lens to use. B1608 and RXJ1131 are accepted, if 'None', user must set remaining parameter manually |
| z_d | Real, only if lens_name='None'. Distance to the lens |
| z_s | Real, only if lens_name='None'. Distance to the source |
| lambda_d | Real, only if lens_name='None'. See 0910.2773v2 equation 5 |
| mu_d | Real, only if lens_name='None'. See 0910.2773v2 equation 5 |
| sigma_d | Real, only if lens_name='None'. See 0910.2773v2 equation 5 |
| name | String, Name for the strong lens |
##Inputs
These parameters and data are inputs to the module, either supplied as parameters by the sampler or computed by some previous module. They are loaded from the data block.
| Section | Parameter | Description |
|---|---|---|
| distances | z | 1D real array, redshifts of samples |
| d_m | 1D real array, co-moving distance in Mpc | |
| cosmological_parameters | omega_k | real, curvature density fraction today (default 0.0) |
| hubble | real, hubble parameter H0 (km/s/Mpc) |
##Outputs
These parameters and data are computed as outputs from the module
| Section | Parameter | Description |
|---|---|---|
| likelihoods | B1608_like | Real, only if lens_name=B1608. Likelihood of B1608 system |
| RXJ1131_like | Real, only if lens_name=RXJ1131. Likelihood of RXJ1131 system | |
| name_like | Real, general case, name from ini file. Likelihood of named system |
