Instrument and Observing Strategy
Please describe the following items, as well as
anything else we need to know to understand how
youre going to make polarization maps
  • Optics
  • band definitions
  • polarization selection
  • Polarization modulation
  • Scan strategy
  • Pointing reconstruction (accuracy)

5
Systematics to consider
Below is a list of potential systematic effects.
Please address whatever effects you can from here
in your talk feel free to add more or
qualify/expand on these. Quantitative limits
(measured, calculated, or estimated) on these
effects would be helpful, as would results of
simulations with your observing strategy that
take them to a power spectrum.
Systematic Effect
Crosspolar beam E ? B
Polarization angle errors E ? B
Pointing errors (on Q/U) E ? B
Main beam asymmetry (before differencing) dT ? B
Sidelobes dT ? B
Instrumental polarization dT ? B
Relative calibration errors dT ? B
Pointing errors before differencing T ? B
Gain drift before differencing T ? B
Optics and spillover T variations dTopt ? B
Scan modulated cold stage variations dTCS ? B
Band shape errors, including modulator effects foregrounds ? B
Others? ?

Issues/Lessons/Concerns
  • For a deployed experiment, what lessons were
    learned?
  • For an experiment in development, what are your
    major concerns? ie, what systematics worry you
    most?
