Talk:Sakuma–Hattori equation

What is the silver point, and where can I find a reference to it on Wikipedia? KickAssClown (talk) 22:52, 5 July 2010 (UTC)

Please define variables
I would appreciate A, B, etc. being defined for the Planckian form. Or are these determined experimentally? —Preceding unsigned comment added by 216.254.57.30 (talk) 08:31, 26 November 2010 (UTC)

A, B, and C are fitting parameters. c2 is a constant. There are estimate values for A, B, and C floating around out there based upon the wavelengths your IR sensor operates at (I think it was from the Australian reference). — Preceding unsigned comment added by 216.53.138.131 (talk) 05:38, 18 March 2015 (UTC)

Relationship to Planck's Law
Hi; I would appreciate some clarity on the relationship of the Sakuma-Hattori equation to the Planck equation. Is this simply an approximation of it? Is Planck's actual Law always a better fit than the "Planckian form" of this formula, just more cumbersome? --RProgrammer (talk) 12:07, 26 July 2020 (UTC)
