The TCS for each baseline with different amounts of missing data ( when ). The performance of joint decompositions methods was almost the same because CMTF-OPT is a special case of CTF-PSF when . Figures 5(b) and 5(c) are local amplifications of Figure 5(a). The sampling ratio of missing values is represented by .
