Screenshots in slides to come are included to indicate key aspects of what attendees saw.
VStar’s appearance has changed slightly since Citizen Sky 2, mostly with respect to background plot color and additional information on phase and mean plots. W Uma phase plots, eps Aur light curve, and
omi Ceti polynomial fit show some of these changes.
