NAZOV / TITLE : The height distribution of the physical properties above a sunspot

ABSTRAKT / ABSTRACT :

We analyzed the photospheric and chromospheric magnetic field properties of a stable 
sunspot belonging to AR 12553 on June 20, 2016. The spectropolarimetric observations 
were acquired with with the GREGOR Infrared Spectrograph (GRIS) at the 1.5-meter
GREGOR telescope and the spectropolarimeter on-board of the Hinode satellite. 
We aim to investigate the magnetic and dynamical properties in the atmosphere above 
the sunspot from photosphere to chromosphere. A spectral-line inversion technique 
was used to infer the magnetic field vector and Doppler velocities from the full-Stokes profiles.
The new modern technique of Computer Vision as pattern recognition was used for image/results processing.
