AD586 Trimming

The AD586 (5V reference) has a trim pin on it.  I would like to use that trim pin to crank the reference output up to 5.12V.  Unfortunately, there is no equation to help me select the proper resistors needed to do this.  Figure1 of the datasheet shows resistors, but doesn't give values.  Are these resistor values known, or are they trimmed at the time of manufacturing?  If they are known, I could use those to come up with my own equation.


Is it possible to get either the equation or the resistor values?  If necessary, approximating will do fine, just need an initial guess for the trim resistors.
