Hi, fundamental constants in gsl are a bit outdated.
Compare the allascii.txt file with http://physics.nist.gov/cuu/Constants/Table/allascii.txt .
The newtonian gravitational constant is particularly neglected: In gsl_const_mksa.h
you can find #define GSL_CONST_MKSA_GRAVITATIONAL_CONSTANT (6.673e-11) /* m^3 / kg s^2 */but the current value is 6.67384e-11 and the value in allascii.txt in the trunk repository is 6.67428 e-11
Best Regards, M. Prevedelli
