AAVSO Acronym of the Day: VPhot

Today's acronym is VPhot – Variable Star Photometry Software

                               

VPhot is an online tool for photometric analysis. You can upload your own FITS images to VPhot or have images taken via AAVSOnet automatically sent to your VPhot 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. VPhot is only available to AAVSO members.

This is just one example of the tools and programs the AAVSO provides to its members, observers and the astronomical community. Please help support these services by contributing to this year's Annual Campaign.

You can mail a check to AAVSO headquarters, or you can make a donation online. Just click the Donate Now button on our home page and select Annual Campaign in the drop down menu.
