# sTools - a data reduction pipeline for the GREGOR Fabry-P\'erot Interferometer and the High-resolution Fast Imager at the GREGOR solar telescope

## TL;DR

sTools is a user-friendly data reduction pipeline designed for the GREGOR solar telescope's instruments, enabling efficient processing and archiving of large solar observational datasets with minimal user intervention.

## Contribution

It introduces a new, standardized, and accessible data reduction pipeline for GREGOR's GFPI and HiFI instruments, streamlining data processing and archiving.

## Key findings

- Provides high-quality, reduced, and image-reconstructed data
- Generates quick-look data and observation summaries
- Stores processed data online for community access

## Abstract

A huge amount of data has been acquired with the GREGOR Fabry-P\'erot Interferometer (GFPI), large-format facility cameras, and since 2016 with the High-resolution Fast Imager (HiFI). These data are processed in standardized procedures with the aim of providing science-ready data for the solar physics community. For this purpose, we have developed a user-friendly data reduction pipeline called "sTools" based on the Interactive Data Language (IDL) and licensed under creative commons license. The pipeline delivers reduced and image-reconstructed data with a minimum of user interaction. Furthermore, quick-look data are generated as well as a webpage with an overview of the observations and their statistics. All the processed data are stored online at the GREGOR GFPI and HiFI data archive of the Leibniz Institute for Astrophysics Potsdam (AIP). The principles of the pipeline are presented together with selected high-resolution spectral scans and images processed with sTools.
