Hello -- unfortunately we had to remove the electromagnetic constants
from cgs.h because the units weren't defined unambiguously. It should
be in the Changelog and NEWS, though, with the following messages:
2009-08-17 Brian Gough <address@hidden>
* const.el: removed electromagnetic constants from cgs, now only
in CGSM
** The header file gsl_const_cgs.h no longer defines values for
electromagnetic units. Applications should use gsl_const_cgsm.h
instead to obtain the values in the CGS-Magnetic system. The
previous values for these units given in gsl_const_cgs.h were
incorrect as the type of CGS electromagnetic system was undefined.
The affected constants are GSL_CONST_CGS_BOHR_MAGNETON,
GSL_CONST_CGS_ELECTRON_CHARGE,
GSL_CONST_CGS_ELECTRON_MAGNETIC_MOMENT, GSL_CONST_CGS_FARADAY,
GSL_CONST_CGS_GAUSS, GSL_CONST_CGS_NUCLEAR_MAGNETON,
GSL_CONST_CGS_PROTON_MAGNETIC_MOMENT, and GSL_CONST_CGS_ROENTGEN.
