Eclipsing binary star TZ Lyr
« on: 16:55:31, 03 May, 2017 »
The data for the following phase diagram for the binary star TZ Lyr was collected during 7 clear nights between 11 April and 2 May 2017.

The two stars comprising this binary orbit around each other with a period of approx 12 hours (12.69)

Images of the star field were 60s duration and one taken around every 2 minutes. The images were standardised and processed in the free software Muniwin which produces file suitable for uploading to the BAA database or the aavso database.

The phase diagram was produced using Peranso software.

Nice curves.
Have you tried/used AstroimageJ or FotoDif for curve creation ?

Thank you Tapio. I haven't heard of those two so will have a look. The reason I have chosen Muniwin is that it was recommended to me by the manager of the BAA database and does readily produce files to directly upload to that database as well as the aavso database. Do those programs have any particular advantage.

Don't know if they have any advantage in that process (uploading data to aavso).
But AstroimageJ can do many things, calibrate, plate solve etc. (must admit that I haven't used it so much)
And Fotodif is a real simple curve creation software.

Thanks for that Tapio. I have just tried FotoDif and although there are some freezing points if you make a wrong entry, I rather like it. I'm not sure I can use it for uploading data in the correct format for the BAA it is good for personal use. I rather like the facility to average a number of data points to get a smoother graph. The graph below shows just my last night's readings.

As soon as I get some more time I will have a play with the other program.
Thanks again.
