Profiles of intensity values in the set of synthetic homogeneous atmospheres (solid lines) computed for the various disk features and PK-010 bandpass. In the various sub-panels, the different atmospheres are identified by colors and labels: yellow, green, blue, violet, and black show bright plage, plage, enhanced network, network, and quiet Sun atmospheres, associated with models P to B, respectively. Distance from disk center is given in disk radius units. The dashed lines show the profiles of intensity values in the various atmospheres after their convolution by the model PSF.
