Spatially averaged line profiles of Ca II 8542 Å, Ca II K, Mg II k, and Hα expressed as brightness temperature Tb for the model atmosphere and our observations. Blue: observations; red: model atmosphere at full resolution; green dashed: model atmosphere spectrally degraded to match the resolution of the observations. Panels a–d: spatial averages for the entire model FOV. Panels e–h: spatial averages for a weakly magnetized patch only. The Hα and Mg II k lines are not degraded spectrally.
