I need help learning to use Phoebe. The version I have is 0.31a running on a Windows 7 Pro system. Any suggestions?
The oldest downloadable version of Phoebe looks to be 1.0. I've used it but found it to be pretty buggy and submitted a bug report but it looks like they don't support that version anymore. I found it only can be run a few times before the lightcurves don't display properly. I had to kill the app, restart it, and load my data to continue working with it. The visualization of the binary also didn't work for me. But I was able to model an W UMa type binary and get reasonable results. I abandoned that version in favor of learning to use their latest 2.4 release.
The 2.4 release doesn't have the nice user interface of 1.0 and you need to use Python to access its functionality. That's unfortunate as the 1.0 interface was pretty easy to use. Using Python isn't bad, especially if you are familiar with programming in Python. They have recorded workshops on how to use Phoebe, the most recent one being last year's: http://phoebe-project.org/workshops/2022june/materials. The easiest way to learn it is via Jupyter notebooks, which you can download from their workshop pages.
They had another workshop this year but the recordings don't appear to be available yet.
Hope that helps,
