Comparison of thermal instability theory with MARFE density limit experiment in TEXTOR

The density limits of shots in TEXTOR [Tokamak Experiment for Technology Oriented Research] that ended in multifaceted asymmetric radiation from the edge (MARFE) are analyzed with respect to several thermal instability theories\footnote{ W.M.
