Flux vs Phase

Display flux as a function of orbital phase for phase-folded light curves.

Overview

The Flux vs Phase viewer (registry name lcviz-phase-viewer) displays flux against orbital phase computed from the ephemeris defined in the Ephemeris plugin. One phase viewer is created automatically for each ephemeris component added.

The x-axis spans [-0.5, 0.5] in phase units by default, and the viewer stays synchronized with the time viewer through the shared ephemeris.
