Table A2.

An overview of the amount of data adjusted by each method. Each flag corresponds to a specific method: interpolation of missing data (1, Sect. 4.2), averaging multiple data-points (2, Sect. 4.3), outlier detection (3, Sect. 4.4), and proxy interpolation (4, Sect. 4.5). The flags are further described in Section B.7. Generally, all interpolated data are detected as outliers and interpolated by our coherency interpolation scheme. The CDS instrument does not provide daily observations, and, as such, has most data points interpolated. The last column corresponds to the number of channels in the instrument.
