Level 1 processing

• camera non-linearity correction
• dark current subtracted
• gain correction applied
• apply polarization demodulation matrix to construct Stokes I, Q, and U
• apply distortion correction
• align each camera to center, rotate to solar north, and combine cameras
• coordinate transformation from cartesian to tangential polarization to separate sky polarization from corona

Level 2 processing

• remove sky polarization
  • use method specified in config file, either "subtraction" (default) or "sine2theta"
• correct for sky transmission
