The GRIS archive, the 1.5 μm level2 data, the GREGOR telescope, the Adaptive Optics system and the GRIS instrument.

The spatial and spectral quality of the GRIS data was studied in detail by Borrero et al. (2016) and Franz et al. (2016).

For visualization and standard calibration of GRIS level1 data you may download an IDL-GUI which requires sswidl or

runs as a virtual machine without a licence in IDL8.5 and higher. The installation procedure is described in the manual.

If you make use of this archive please acknowledge the GRIS & GREGOR projects by citing the abovementioned

publications and add this paragraph to the end of your manuscript.
