  * Present: Joy, Jacques
  * Minutes: 
    * Joy and Jacques go over the Optics section of the systematics listed [[:preliminary_list_of_systematic_effects_to_consider#systematics_list | here]]
    * IP is separated in two effects: sky T->P leakage from sky T converted to sky P through IP, and  polarization load/noise coming from instrument emitted T converted to P through IP (ex: mirror T emissions converted to P through lens IP).
    * Many optic effects are hard to assess without a more detailed knowledge of the optical chain
    * Overall, Jacques thinks the optical beam systematic effects will be very important and need to be simulated and studied in details.
    * Note that end-to-end beam calibration on the ground will not be possible as the instrument cannot be cooled on the ground.
    * For pointing, given the probe's beam size, effects should be similar to what was studied for Core.
