| Abstract: |
The Nançay radio telescope (NRT) is a national facility, the fourth single-dish instrument in the world for its collecting area. It provides spectral and/or continuum data in the frequency range 1.06 to 3.5 GHz, and covers various scientific fields in solar system astronomy (comets, planets. . . ), galactic astronomy (pulsars, late type stars, star forming regions, microquasars. . . ) and extragalactic astronomy (HI in galaxies, large scale structure of the universe, quasars. . . ). Two on-line databases and a general archive are being designed to fullfill the VO standards: HIG (HI profiles of Galaxies) contains reduced 1-D 21-cm spectra for ∼4500 galaxies; NAP (Nançay Archive of Pulsars) provides a few thousand pulse profiles from regular timing observations of ∼40 pulsars; NRTA (Nançay Radio Telescope Archive) will host all NRT data from the backends (correlator, digital spectrometer and pulsar dedispersors). Most of the data consist of dynamical spectra (time-frequency domain). The package which is used for the database management and for the data-processing pipeline is the Pleinpot software, which has been developed for the hyperleda database. |
