W. M. Stacey presents stability criteria for the thermal instability based on a linear one-dimensional (1D) slab model including the effects of ionization recombination [Phys. Plasmas {bold 3}, 2673 (1996)], large radial gradients and rotation [Phys. Plasmas {bold 3}, 3032 (1996)] and external edge heating [Phys. Plasmas {bold 4}, 134 (1997)]. The second paper is incorrectly presented as a two-dimensional (2D) analysis. The hypothesis for the poloidal asymmetry of the multifaceted asymmetric radiation from the edge (MARFE) is based on a misinterpretation of the linear results and contradicted by our own linear analyses in a 1D cylindrical [Phys. Plasmas {bold 1}, 2623 (1994)] and a 2D tokamak model [Plasma Phys. Controlled Fusion {bold 39}, 423 (1997)]. The explanation for the evolution into a detached plasma and for MARFE suppression by external edge heating are interesting hypotheses, supported by experimental observations. However, a 1D linear analysis does not offer the basis to support these hypotheses theoretically.{copyright} {ital 1997 American Institute of Physics.}
