This tool provides model-based Star-Planet Separation, Star to
Planet Relative Flux and Planet Polarization (in visible-reflected
light). The evolution with time of these parameters are displayed with
histograms or with 3D scatter plots (X, Y, color). PNG images and data
can also be saved.
The computations use parameters from the database when available.
Otherwise, default values (in color on the web page) are provided from
an Earth-like planet model (warning: they could be far from actual
All orbital and albedo parameters can be modified by the user.
- The computation of Contrast ratio and Polarization need albedo
values (wavelength dependent), generally unknown. The wavelength
dependency is taken into account through the choice of albedo values.
