VOMegaPlot Client-Server

VOMegaPlot Client-Server, has been developed for visualizing astronomical data that is available in VOTable format. It has been specifically optimized for handling large number of points (in the range of millions) without actually storing these huge files on the user's machine. It has the same look and feel as VOMegaPlot and both these tools have certain common functionality.

VOMegaPlot Server is the hosting end of the VOMegaPlot Client-Server which handles the requests made by VOMegaPlot clients. When the client sends the plotting request, plotting of datasets happens at the server end, while only the plotted image is transferred back to the client.

.

VOTable file is to be converted to voi and cfo files.
(Run the server jar using the -parse option for this)

Server loads the requested voi file, makes a plot and sends an image to the client

It uses Ptplot 5.2, a 2D data plotter and histogram tool implemented in Java. Also, it makes use of cds.astro (Astronomical coordinate manipulation) package for projection maps.

VOMegaPlot Client-Server 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 and with support from the European AVO project. 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.
