Hi Laura,
You can fold a light curve on a fixed ephemeris, but AIJ does not current solve for the best fit ephemeris or produce periodograms. To fold on a fixed ephemeris, use:
Multi-plot_Main->X-axis->"Set epoch and period..." to set those parameters.
Then select:
Multi-plot_Main->X-axis->"Show X-axis as days since Tc"
Note: there are other X-axis phasing options which work for display, but if you are fitting the transit, you will need to select the "days" since Tc option.

Hello,
Is there a way to fold multiple curves into one in AstroImageJ by setting the period manually? And can AstroImageJ determine which period gives the best folded curve/produce periodograms?
Thanks!
