SSTRED: Data- and metadata-processing pipeline for CHROMIS and CRISP

Context. Data from ground-based, high-resolution solar telescopes can only be used for science with calibrations and processing, which requires detailed knowledge about the instrumentation. Space-based provide science-ready data, are easier to work researchers whose expertise is in interpretation of data. Recently, data-processing pipelines ground-based instruments have been constructed. Aims. We aim observers a user-friendly data pipeline Swedish 1-meter Solar Telescope (SST) that delivers together metadata needed proper archiving. Methods. briefly describe CHROMospheric Imaging Spectrometer (CHROMIS) instrument, including its (pre)filters, as well recent upgrades CRisp SpectroPolarimeter (CRISP) prefilters polarization optics. summarize processing steps raw cubes FITS files. report compensations imperfections detail. Misalignment Ca II due wavelength-dependent dispersion identified, characterized, compensated for. intensity remove or reduce effects filter transmission profiles elevation changes. present REDUX, new version MOMFBD image restoration code, multiple enhancements features. It uses projective transforms registration detectors. how CRISP CHROMIS The output delivered files, compliant SOLARNET recommendations. cube coordinates specified within World Coordinate System (WCS). Cavity errors distortions WCS wavelength coordinate an extension existing notation. establish notation specifying reference system Stokes vectors directions. CRIsp SPectral EXplorer (CRISPEX) data-cube browser has extended accept SSTRED take advantage metadata. Results. mature imaging instruments, developed SST/CHROMIS spectrometer SST/CRISP spectropolarimeter. well-characterized, science-ready, archival-quality files well-defined REDUX CRISPEX, freely available through git repositories.
