Waves in the chromsophere and TR
Transition region waves/oscillations(3.10)
Network line profiles
Peter, 2001, A&A 374, 1108.
Broad components are a common factor om emission profiles from 4x10
K to 10
Peak broad component contribution in middle transition region.
Width of of broad component increases with increasing T
Broad component blue shifted compared to core but still (usually) red-shifted.
Cell center emission best described by single Gaussian
