The IIA Center for Astronomical Data and Software (CADS) is a proposed one stop shop for data from various facilities of IIA and a local mirror for international data. IIA has always been a source of astronomy data, with facilities ranging from Kodaikanal solar observatory (archival data from late 19th century onwards), to more recent Vainu Bappu Observatory at (VBO), Kavalur and Indian Astronomical Observatory (IAO) at Hanle. Space missions like the TAUVEX and UVIT/Astrosat are under various stages of completion. Infact, CADS originated from activities related to the TAUVEX mission, where IIA scientists and engineers are working on data simulation,data pipeline, data archival and dissemination.
The center shall not be limited to a search and download interface. Our aim is to provide open data access plus cross mission development and support center for the scientific community, so as to maximize the scientific exploitation of every observation obtained. The CADS staff would consist of professional astronomers, PDFs and software programmers. CADS is expected to be a training ground for novice programmers, before they enter into "Brand Bangalore" domains. Some of the future plans are detailed below.
TAUVEX is an Indo-Israeli mission to image the sky in Ultraviolet (UV). Expected to fly by the end of 2009, it will map large areas of the sky in the wavelength range 1200 - 3300 A. Raw data from the spacecraft will be processed by the automated data pipeline software and fed into a searchable database. Currently in the last stage of completion, these activities form the precursor for CADS. The TAUVEX software team is also developing an abundance of other sophisticated tools to support and enhance astronomical research. A science center will be built around the TAUVEX data archive in subsequent years.
One of our first projects is to set up a virtual solar observatory. Data from various solar observatories around the country is monitoring the sun in optical and radio frequencies. We plan to bring these data together into one location and provide a nearly-real time data access.In addition to the current images and spectra of the sun, the center shall also provide a searchable index for archival solar data.
Collaborations:Much of the software development is expected to be carried out in collaboration with the Virtual Observatory team, both from India and abroad. Other tentative collaborators include the Center for Astrostatistics at PennState.
