VPhot is an online tool for photometric analysis. You can upload your own FITS images to VPhot or have images taken via the AAVSOnet robotic telescope network automatically sent to your VPhot account.
To use VPhot you must:
- Be an AAVSO member (Apply for membership.)
- Have an AAVSO observer code (Apply for an observer code - its free and automatic)
- Be logged into our web site. (Register for a web site account.)
All VPhot processing is done via a web browser. All of the basic photometry tools exist (stacking, time series analysis, control of annulus', transformation, etc.) and the algorithms have been rigorously checked and confirmed to be of the highest quality. Results of the processing are automatically exported in AAVSO Extended Format, meaning you can directly load them into our database via WebObs without having to make any changes to the data file.
Members can download the user guide here.
We also have an online VPhot Forum for your questions, comments and suggestions.
