on the call: Karl, Shaul, Brendan, Julian, Kris

• Pointing: star camera backed by rate gyros planned.
  • actions: Julian: get a little more detail from Reijo,
  • Planck Explanatory Supplement Link
  • Eric Hivon Pointing error T to B leakage
    • Question: where does the eqn. at the bottom of Slide 21 come from? (maybe in QuickPol paper)
    • Assuming that equation is true, Slide 22 shows a result summary. for 1 arcsecond
  • Action to Eric: at 1“ pointing noise, what is ratio of blue to gravitational signal at r=1e-4 ?
  • Action to Brendan: look up Gaia info
• Far sidelobes:
  • Karl interacting with Maura Sandri to try to determine reliability of GRASP sims.
  • orbit around L2 introduces a trade between fuel consumption to keep a tighter orbit, and Earth/Moon sidelobe pickup
  • need some input in a month.
