VStar 2.16.4 Revision 1208

Star data visualization made easy
VStar is a reliable and Java-based utility that will help you to visualize and analyze variable start observation plots.

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.

Main features:

  • 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).
