Distribution of physical properties along the L1 loop. Panel a) shows dependence of the loop width on the loop length. Derived radii with the Gaussian Fitting increases from 2.3 Mm to 3.7 Mm. Panel b) shows distance between neighboring turns. Panel c) shows the critical value for kink instability criterion for large aspect ratio loops. Above the critical value of 1, this criterion is satisfied and the occurrence of the kink instability is likely.
