For a sphere, brightness varies as (1+cos(Phs))  (100%=0 deg.)
This makes a factor of two from 50% to 100% (but not linear!)
Magnitude is 2.5 * LOG10(lightlevel), i.e. 0.75 magnitudes.

QS = Molczan - 0.75

But Molczan has estimated (d) or normal condition (v) standard
magnitudes, whereas Mike's QuickSat files have 'best ever' values,
so the difference can be much larger.
