The standardized magnitude for the variable is given by
Vstd = (Vins - Cins) + Cstd
where Vins is the instrumental magnitude of the variable, Cins is the instrumental value of the comparison, and Cstd is the chart magnitude for the comparison (or the equivalent for ensemble photometry).
Note that 'standardized' does NOT mean that Landolt Standards were used as comparison stars.
