Dear colleague, Some of our colleagues have requested us to send a subroutine for the fitting fomula in our paper "Relativistic Thermal Bremsstrahlung Gaunt Factor for the Intracluster Plasma. III. Analytic Fitting Formula for the Nonrelativistic Exact Gaunt Factor" (submitted to ApJ; astro-ph/9906467). We will send this subroutine to you. We would be most delighted to hear whatever comment you might have on our work. Yours very sincerely, Naoki Itoh **************************************************** Naoki Itoh Department of Physics Sophia University 7-1 Kioi-cho, Chiyoda-ku, Tokyo 102 Japan Telephone (81 or 0) 3 3238 3431 FAX (81 or 0) 3 3238 3341 **************************************************** CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC C C C THERMAL BREMSSTRAHLUNG GAUNT FACTOR ANALYTIC FITTING FORMULA C C C C GF = sum{ GAMMA^i * U^j }, { i,j = 0 - 10 }.
