CHROMIS Ca II NB continuum (median) intensities of restored data (individual scans), with and without temporal correction as indicated in the legends. The WB calibration curves are the fit functions (shown in Fig. 8a for the 2016 September 19 data), scaled to approximately match the disk center continuum intensities. The dot colors refer to data with no correction (green), the old correction based on the WB intensity in the data set itself, and the correction based on a fit to disk center data (red). (a) Data from 2016-09-19, μ ≈ 1 (near disk center). (b) Data from 2019-06-21, varying μ.
