Flowchart of the COMAP pipeline, from raw Level1 data to final power spectra. Data products are shown as darker boxes and pipeline code as lighter arrows. l2gen performs the time-domain filtering, turning raw data into cleaned Level 2 files. accept_mod performs scan-level data selection on cleaned data. tod2comap is a simple binned mapmaker. mapPCA performs a map-level PCA filtering. Finally, comap2fpsx calculates power spectra as described by Stutzer et al. (2024).
