VStar is a multi-platform, easy-to-use variable star observation visualisation and analysis tool. Data can be read from a file or the AAVSO database, light curves and phase plots created, period analysis performed, and filters applied. Plugins can be developed, e.g. to make additional observation sources available.

    Hello One useful add-on in the DC DFT standard scan plots is to allow the user to make the values for user-selected top hits stay on the graph so that we don't have to manually input them through image editors. Thank you,Tomas
