The ESA/NASA Solar Orbiter successfully launched in February 2020, carrying the Polarimetric and Helioseismic Imager (SO/PHI) instrument. This instrument utilizes differential imaging of polarized light emitted by the Sun to deduce the photospheric magnetic field and line-of-sight velocity. The article presents the architecture of the on-ground pipeline for HRT, which can reduce raw images to the full Stokes vector with a polarimetric sensitivity of 10(-3).I-c or better.
The ESA/NASA Solar Orbiter space mission has been successfully launched in February 2020. Onboard is the Polarimetric and Helioseismic Imager (SO/PHI), which has two telescopes, a High Resolution Telescope (HRT) and the Full Disc Telescope (FDT). The instrument is designed to infer the photospheric magnetic field and line-of-sight velocity through differential imaging of the polarised light emitted by the Sun. It calculates the full Stokes vector at 6 wavelength positions at the Fe I 617.3 nm absorption line. Due to telemetry constraints, the instrument nominally processes these Stokes profiles onboard, however when telemetry is available, the raw images are downlinked and reduced on ground. Here the architecture of the on-ground pipeline for HRT is presented, which also offers additional corrections not currently available on board the instrument. The pipeline can reduce raw images to the full Stokes vector with a polarimetric sensitivity of 10(-3).I-c or better.
