Some aspects of the analysis of vector magnetograms and application to collaborated measurements
Abstract
Simultaneous vector magnetograms were obtained with the magnetographs of the Potsdam Solar Observatory "Einsteinturm" and the Sayan Observatory (Irkutsk). For the study the leading spot is selected in the active region SD 164 (NOAA 4216) on June 24, 1983. A comparison of the magnetograms shows a good correpondence in the field strengths as well as in the field azimuths. The mean vertical gradients in the umbra were found to be about 0.32 G km-1. The disribution of the vertical gradients reflects a return flux topology of the magnetic field around the spot.
