Detailed Description

* physical constants used by Cloudy, mostly taken from
* >>refer       phys    const   Mohr P.J., Taylor B.N., & Newell D.B., Codata 2006, http://www.physics.nist.gov/constants
* <BR><BR>
* NB - these are all printed with the "print constants" command, 
* which is in parse_print.cpp, so any new constants
* added here must also be added to the prt_constants routine 
* this is in the func_test case in the auto test suite

const double TRANS_PROB_CONST = PI4*HPLANCK*FINE_STRUCTURE/ELECTRON_MASS

This is the constant used in converting oscillator strengths to As. The formula is Aul = TRANS_PROB_CONST * f(u,l) * wavenumber^2. TRANS_PROB_CONST is 0.667025
