Hello,

First, AstroImageJ has been a great help in my work, thank you.

Second, I was making a light curve of an exoplanet transit and the
transit feature showed up inverted. I know that can happen if one subtracts the target
from calibrator instead of the other way around, so is it possible
for someone to accidently do this with AstroImageJ ?

I take it that the units of "rel_flux_T1" is in magnitudes, it could be useful
if instead one used percentage flux change instead.

Thank you
David
