Generation of Fully Phase-Controlled Two-Photon Entangled States

Fig. 4, panel (d)

Contrast measurement in the X basis: $\langle XX\rangle$ against phase (degrees) as the phase is scanned, with error bars. The black curve is a fit of the caption's form $A \sin(x + \phi)$ to these points, made for this panel in place of the printed fit.
