(25) The Infrared Handbook
An excerpt from The Infrared Handbook, chapter 1. Radiation Theory, 1.2.7 Pocket Calculator programs, page 117.
… Several pocket calculator programs are presented here. They were written for the HewlettPackard HP25 and the Texas Instruments SR56 and SR52 calculators. The programs reflect differences in programming between Reverse Polish Notation (RPN) and Algebraic Operation (AO) systems , as well as differences resulting from calculators which can and cannot store programs on cards. Table 115 gives the equations, units, a catalog of the programs, and initialization and starting procedure. In most cases some of the storage registers need to be filled at the start with terms indicated by quantities not in parentheses. Those registers which show a parenthesized expression are used in the calculation, but do not need to be initialized. In the programs for integrals, a value of e, the allowed fractional value of the next term of the series, needs to be entered. For most problems and their required accuracies, 109 is an appropriate value for this . For additional information on programming pocket calculators, see References [112]. equations, units, instructions pages 118 thru 120 the program listings pages 122 thru 125 page 122 Table 116 StefanBoltman Law Table 118 StefanBoltman Law  Photons Table 120 M_{λ} and M_{λ} ⁄ ∂T Table 122 M_{qλ} and ∂M_{qλ} ⁄ ∂T page 123 Table 123 M_{v} and ∂M_{v} / ∂T Table 124 M_{qv} and ∂M_{qv} / ∂T Table 125 _{y1}∫^{y2} M_{y} dy Table 126 ∂M_{∆λ} / ∂T = _{y1}∫^{y2} (∂M_{y} / ∂T) dy page 125 Table 128 M_{q∆λ} = _{y1}∫^{y2} M_{qy} dy BEST!
