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