Distributions of temporal mean values of coherence (stack coherence) in path a 131 and b 23. The area with stack coherence values of less than 0.4 is masked by black color. The red stars indicate reference pixels in each path. The reference pixels have stack coherence values of 0.56 in path 131 and 0.51 in path 23
