14. The FS Preprocessor Postel Projection of Dopplergrams Quality control: Frame rejection (based on NaN values) Glitch/cosmic-ray recognition and removal (deviation from temporal trends) Conformation to appropriate rotational profile Spatial filtering/condensation (what is this?) Spectral filtering: extraction of the 2.5-4.5 mHz band ** Possibility of binning down to 90sec. Cadence (Nyquist frequency of 5.6mHz)
