Expressions for X-ray fluorescence spectroscopy described in a previous paper, were extended for the calculation of the fluorescence intensity of a thin specimen, providing a detector count rate with a precision of better than 0.2%. The results are presented in the form of delta(xi(1)eta(1 - )xi(2)eta(2)) where eta(1) and eta(2) are the standard functions common to all cylindrical geometry systems of any size, delta, and where xi(1) and xi(2) are user calculable coefficients.
