• Scanning strategy generated with TOAST with:
  • precession: 22 deg, 11.75hours
  • spin: 61 deg, 2mn
  • duration and sampling rate: 366 days, 85Hz

• Focal plane simulation (with QuickPol): 8 Planck-like beams of FWHM = 7.68
  • nominal: 8 detectors rotated by (0,-90) or (-45,45deg) wrt the scan direction
  • MonteCarlo simulations: same as above with random error on each orientation angle
    (Gaussian distribution of mean 0 and rms = 1deg)

• CMB only, no noise, no foreground, no mask

In the plot below, are shown the leaked power spectra seen when auto-correlating the map obtained when combining the 8 detectors, with either the nominal orientations or the MC error ones. Green long dashes: nominal, colored shorter dashed: first 4 simulations, short gray dashes: next 6 simulations.
