Line 13: == Derivation for a circular orbit == [[File:Doppler Shift vs Time.~~jpg~~svg\|frame\|Radial velocity curve with peak radial velocity ''K''=1 m/s and orbital period 2 years.]] The peak radial velocity <math>K</math> is the semi-amplitude of the radial velocity curve, as shown in the figure. The orbital period <math>P_\mathrm{orb}</math> is found from the periodicity in the radial velocity curve. These are the two observable quantities needed to calculate the binary mass function.<ref name="podsiadlowski" />
