Explanation
This small module was written for CosmoSIS.
Supernova type IA measurements are a standard(izable) candle
that can be used to probe the relation between luminosity distance
and redshift. At low redshifts this directly probes the Hubble parameter,
H0.
The Riess et al 2.4% solution measurement of H0 is used in this module.
##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 |
---|---|
mean | float, replace the standard value measurement h = 0.7324 with a custom one for simulations (default 0.7324) |
sigma | float, replace the standard value error on h of 0.0174 with a custom one (default 0.0174) |
##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 |
---|---|---|
cosmological_parameters | h0 | real, hubble parameter H0/(100 km/s/Mpc) |
##Outputs
These parameters and data are computed as outputs from the module
Section | Parameter | Description |
