VOPlot

VOPlot is a tool for visualizing astronomical data. VOPlot is developed in JAVA, and acts on data available in VOTABLE, ASCII and FITS formats. VOPlot is available as a stand alone version, which is to be installed on the user's machine, or as a web-based version fully integrated with the VizieR database.

VOPlot uses Ptplot 5.2, a 2D data plotter and histogram tool implemented in Java. Ptplot has been developed at Electrical Engineering & Computer Science department at the University of California, Berkeley and is freely available under a BSD style license.

VOPlot can be invoked by selecting the Plot (VOPlot) option while using VizieR.

VOPlot has been developed as a part of the Virtual Observatory - India initiative by Persistent Systems Ltd. (PSL) and the Inter-University Centre for Astronomy and Astrophysics(IUCAA), in collaboration with Centre de Données astronomiques de Strasbourg (CDS), Strasbourg. The collaboration between VO-I and CDS extends to several related projects. The VO-I project is supported by the Ministry of Communication and Information Technology of the Government of India.

The Web Based Version of VOPlot

VizieR, developed by Centre de Données astronomiques de Strasbourg(CDS) provides access to the most complete library of published astronomical catalogues and data tables available on line, organized in a self-documented database. Query tools allow the user to select relevant data tables and to extract and format records matching given criteria. Specific care has been taken for optimizing access to some very large catalogues such as Guide Star Catalogs, the USNO-A2, 2MASS.

VOPlot is fully integrated with VizieR, and it allows the user to visualize data extracted from any of the catalogues from the database. Presently it can be used to display the distribution, as a histogram, of any data field, or to plot two data fields against each other. Simple transformations can be applied to the extracted data. The visualized portion can be just a dynamically selected subset of extracted data. Some simple statistical information about the selected data can be obtained.
