G-band image of the disk center which was taken on 24.4.2010. The images are speckled using the KISIP speckle code. Telescope: VTT, post-focal instrumentation: G-band 1nm filter, additional optics to devide and focus the beam in front of the TESOS spectrometer, PCO 4000 camera.

TESOS Fe I 709 nm line data: spectral plane taken in the blue wing, line center, and red wing (left, middle, right panels, resp.). FoV of ~40 arcsecs. Data after the photometric corrections but without any additional destretching and aligning corrections apllied so far. Telescope: VTT, post-focal instrumentation: the TESOS 2D spectrometer in the I-mode.
