Overview of the Data Reduction Pipeline. The data reduction pipeline for the MOF-based synoptic telescopes consists of three modules, which, respectively: subtract the dark; compute and correct for the flat field frame . evaluate and correct for the atmospheric extinction and the orbital trend; compute and subtract the leak calibration frame ; The registration module consists of other three modules,which, respectively: compute and apply the polarization registration (σ⁺,σ⁻), compute and apply the wings registration (B,R), compute and apply the channels registration (K, Na). The final module computes the K and Na line-of-sight magnetogram () and Dopplergram () synoptic maps.
