Introduction

Formulae for the R Value

The R values, i.e. the x axis in the drawing area, are calculating by the following formulae when a new graph has drawn:

           ln (TINY)
RA  =  -  -----------
             alpha

and

                n * ln (RA)
R   =  RA  +   -------------
                   alpha

Normally the minimum alpha value of all orbital data is chosen for alpha.
