Notes. The first column is the paper reference, the second is the spectral lines used for the study, the third is the region analysed, the next six columns correspond to the minimum, maximum, and mean of the magnetic field strength and inclination, and the last column is the average temperature. When the authors do not study a parameter, the cell is empty. The meaning of the subindices are: sc and wc from Rüedi et al. (1995) are strong and weak atmospheric components, respectively; FR from Louis et al. (2012) means LB in formation; N and S from Falco et al. (2016) means the north and south area of the LB; and * from Falco et al. (2016) means that the temperature was calculated in the biggest granule of the northern part of the LB. The superindices from Lagg et al. (2014) mean that the values are calculated in the interior and in the boundary of a granule in a LB.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
