GREGOR: daily H-alpha GSJC movies
This website contains H-alpha movies of the GREGOR slitjaw system. The slitjaw system is a context imager for the GRIS spectrograph. Most of 2019 is quick-look only (level 0). This means all fits files recorded during the day (including darks and flats) are displayed. A proper data reduction was done for the Mercury transit on 20191111 (level 1). Starting in 2020, L1 data is shown if available and if the observer followed the checklist for taking SJ data. L1 data is dark- and flat-corrected and only science frames are shown in the movie.
The movies are of mp4 format and should play at least in Firefox and Chrome. For any questions and comments, please contact Lucia Kleint.
