Remark on algorithm 644
This remark details correction for errors in the functions which compute the modified Bessel function of the second kind and the log of the gamma function. In both cases these errors cause a loss of precision for a small range of values of the. argument. These routines are used in the calculation of a number of other functions within the package whose accuracy is thus similarly affected.
