I want to present and recommend the new software, Peranso 3. This is the most complete variable star analysis program and also it's easy to use. I used Peranso 2.6 in the last 3 years, but the last update allows direct ZTF data importing, faster analysis and a lot more. You should download and try the trial version available at https://www.cbabelgium.com/peranso/ . In the future, i can even do a tutorial for people who want to learn it assisted. If you have any questions about it, please ask.
