Penumbral Line Asymmetries Using KAOS
Abstract
We analyse and interpret the line asymmetries in a sunspot penumbra at a heliocentric angle of 23°. The data, acquired with TESOS [1] and KAOS [2] at the VTT, is of high spatial (0.5") and high spectral ( λ/∆λ = 250 000) resolution. We observed in Fe I 557.6 nm (g=0) [3].
