Generate and return the unnormalized Gamma-Ray Burst Formation Rate (GRBFR) density based on the estimates of Petrosian et al (2015).
- Parameters
-
[in] | logzplus1 | : The non-negative input scalar or array of arbitrary rank of type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128) containing the natural logarithm of the redshift plus one, \(\log(z+1)\), at which the formation rate density must be computed. |
- Returns
logRateDensity
: The output of the same type, kind, and rank as the input argument logzplus1
containing the natural logarithm of the unnormalized formation rate density of LGRBs at the requested redshift.

- Warning
- The input argument
logzplus1
must be non-negative since a negative redshift is cosmologically undefined.
This condition is verified only if the library is built with the preprocessor macro CHECK_ENABLED=1
.
-
The
pure
procedure(s) documented herein become impure
when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1
.
By default, these procedures are pure
in release
build and impure
in debug
and testing
builds.
