hi long,

published fits to tabulated thermonuclear reaction data are usually done
temperatures less than 1e10k. evaluating those fits beyond this upper bound
can produce silly numbers, hence the clipping and warning. as material at
these temperatures is generally in nuclear statistical equilibrium, 
such clipping is unlikely to significantly impact the evolution.
