VStar is an easy-to-use, Java-based tool that will help you with the visualization of variable star data.
Data can be read from a file or the AAVSO database and plotted as a light curve along with means data and error bars. Phase plots are under development and period search functions are planned
Here are some key features of "VStar":
· Loads data from the AAVSO database and CSV or TSV files.
· Displays light curves and phase plots, along with a mean curve.
· Data can also be viewed in tabular format.
· Views can be printed and saved.
· Period analysis (Date Compensated Discrete Fourier Transform).
· Polynomial fitting.
· Filtering function.
· Plug-in architecture (observation sources, period analysis, filtering, other tools).
Requirements:
· Java
