In a recent paper Stellmacher and Wiehr (1973) discussed in detail the discrepancies between ‘continuum-’ and ‘line-profile facula models’. Their calculations show that continuum models (e.g. Kuz'minykh, 1962; Schmahl, 1967; Chapman 1970; Wilson, 1971) encounter the problem that the facula contrast increases towards the limb but decreases with wavelength λ. This discrepancy evidently cannot be due to NLTE effects since it concerns the continumm data.
