Re: CERES modes
Fixed Azimuth Plane Scanning (FAPS) has scan lines perpendicular to the path of the satellite, while Rotating Azimuth Plane Scan (RAPS) lines are at a wide range of angles with respect to the satellite's path. An instrument operating in RAPS has increased spectral darkening of the transmissive optics. The Cross-Track instrument is recommended by CERES, since the spatial distribution of footprints is uniform.
