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