Otherwise Iris is free and will measure a light curve for you.

I've never had any luck with Iris in the past, been too hard to use. But that tutorial you linked to looks quite promising. I will try that.

I don't mind paying something, for AIP4WIN, if I know it's going to do what I want, but I haven't confirmed it will (couldn't find specs on capabilities of AIP4WIN).... but if you use it to get a light curve from a sequence of FITs files then perhaps that's the confirmation I need

Thanks for your reply.
