Hi, I am just starting out. I have captured some images of variables and I would like to practise the photometry measurements before I start submitting observations. Can I use VPhot for practise or will it automatically submit my results?

I truly hope someone can help me with this.

When I upload Fits from Google Drive I keep getting what looks like Static only once have I had a Star image that actually looks like it should.

I keep getting errors with Jason when generating a light curve. As in the software can not read the file.

I am away from my PC at the moment so can upload later images of the problems.

Has anyone else encountered this and is there something I should be doing.

Exotic Practice works fine

https://www.aavso.org/aavso-extended-file-format

It indicate that CMAG and KMAG should be instrumental magnitudes. I have been using Tycho to generate my report and it does put instrumental magnitudes there.
