pixel\n> - band 3 shows the number of images used in the time series inversion for each pixel\n> - band 4 is a proxy for the temporal coherence, computed from triplets (between 0 and rlooks_unw): it is a multilooked version of the proxy for the temporal coherence given in TCoh product\n> - band 5 is a proxy for possible bias, computed from triplets (in rad)\n> - band 6 is number of unwrapped interferograms greater of 8 months per pixel.
