| Abstract: |
In July 2009, the leading spot of the active region NOAA11024 was
observed simultaneously and independently with the ‘Göttingen’ FPI
at VTT and CRISP at SST, i.e., at two different sites, telescopes,
instruments and using different spectral lines. The data processing
and data analysis have been carried out independently with different
techniques. Maps of physical parameters retrieved from 2D
spectro-polarimetric data observed with ‘Göttingen’ FPI and CRISP
show an impressive agreement. In addition, the ‘Göttingen’ FPI maps
also exhibit a notable resemblance with simultaneous TIP
(spectrographic) observations. The consistency in the results
demonstrates the excellent capabilities of these observing
facilities. Besides, it confirms the solar origin of the detected
signals and the reliability of FPI-based spectro-polarimeters. |
