## Synchrotron Functions

The functions described in this section are declared in the header file ``gsl_sf_synchrotron.h'`.

Function: double gsl_sf_synchrotron_1 (double x)
Function: int gsl_sf_synchrotron_1_e (double x, gsl_sf_result * result)
  These routines compute the first synchrotron function x \int_x^\infty dt K_{5/3}(t) for x >= 0.

Function: double gsl_sf_synchrotron_2 (double x)
Function: int gsl_sf_synchrotron_2_e (double x, gsl_sf_result * result)
  These routines compute the second synchrotron function x K_{2/3}(x) for x >= 0.
