SolPol

Instrument manual and data processing algorithm for the NOA/UH - Solar Polarimeter (SolPol)

This repository contains everything related to the operation, characterization and data manipulation of the SolPol - Solar polarimeter, as operated by the NOA-ReACT team. The instrument was conferred to the National Observatory of Athens by the University of Hertfordshire in the framework of the D-TECT/ERC project.

General info:

• is a passive polarimetric ground-based instrument that targets directly the Sun
• has measuring capabilities of a few parts per million (ppms) in linear polarization and of the order of $10^{-7}$ in circular polarization
• is based on the existing design of the PlanetPol high sensitivity polarimeter as described in Hough et al., 2006
• usage under laboratory conditions is described by Martin et al., 2010

Operation

• Extensive measurements and tests between August 2018 to November 2022
