Table 1: Relevant parameters of $\theta$ Cen and $\alpha$ Cen A.
Table 2: Sample data sets. N is the number of scans.
Table 3: $\kappa$ coefficients measured for $\theta$ Cen and $\alpha$ Cen A.
Table 4: Reasons for the rejection of $\theta$ Cen and $\alpha$ Cen A interferograms during the processing. The lower part of this table corresponds to the selection criteria related to the atmospheric piston effect.
Table 5: Statistical properties of the $\theta$ Cen and $\alpha$ Cen A sample batches. The values obtained when disabling the selection of the interferograms based on their piston properties are given in brackets for comparison.
