I'm so impressed with how much AstroImageJ CAN do, and how well supported it is here and elsewhere that I'm hesitant to ask for anything new!
Has anyone figured out how to do time-series photometry with two photometric filters -- say a multi-band time series on an eclipsing binary or RR Lyrae star?
I used to be able to do this with MaxIm DL, but multi-band photometry is no longer working for me. I find that this is useful for demonstrating the difference between exoplanet transits and eclipsing variables, and for prompting students to think about the brightness and color changes happening in short-period pulsators. I'll attach a B & V time series of an RR Lyrae star from AAVSO I did a few years ago as an example.
I can run a pseudo multi-band time series by opening an image sequence in two filters, but when I enter the comp star magnitudes, they are in one band or the other, so not entirely accurate, and the plot doesn't differentiate between the two series except by their Y-axis offset.
If anyone has tackled this, I'd be delighted to learn how to do it in AIJ.
