The Advanced Satellite for Cosmology and Astrophysics
(ASCA) was launched on 20 February 1993, ceased observing on 14
July 2000, and re-entered the Earth's atmosphere on 2 March 2001.
During its life, ASCA performed 661 observations of objects
designated as active galactic nuclei (AGNs). The Tartarus (Version 3.1)
database contains events files, images, spectra, and light curves for 611 of these
observations. Results from rudimentary spectral fitting are also provided.
