The Faint Object Camera (FOC) aboard the Hubble Space Telescope (HST)observed 26 individual active galactic nuclei (AGNs) in ultraviolet imagingpolarimetry between 1990 and 2002. Tremendous progresses have been made thanksto those high spatial resolution, high signal-to-noise ratio observations, suchas the identification of the location of hidden active nuclei and the threedimensional arrangement of polar material within the first hundred of parsecsaround the central core. However, not all AGN observations have been reducedand analyzed, and none in a standardized framework. In this lecture note, wepresent our project of downloading, reducing and analyzing all the AGN HST/FOCobservations that were achieved using a consistent, novel and open-accessreduction pipeline. We briefly present our methodology and show the first,preliminary result from our reduction pipeline: NGC 1068.

The best broths are cooked in the oldest pans: revisiting the archival HST/FOC observations of quasars
