ESO NTT Science Archive

The ESO Archive Database contains all observations performed with the ESO NTT (EMMI/SUSI) telescope since April 1, 1991. The observations themselves are kept in an off-line archive and have, each, a proprietary period to the original observer of one year. Data sets can be requested after this period by the general astronomical community (to retrieve offline data you have to register as an archive user). Images and spectra are stored in the archive in unreduced (raw) form in adition to Calibration and auxilliary data. The Database query result shows a brief description of each of the scientific observations in the archive.
