Comparison of C-band average coherence in 24 and 48 days ascending interferograms (a-c and b-d respectively) of the Sentinel-1 Terrain Observation by Progressive Scans (TOPS) and RSAT2 Wide Ultra Fine 12 (U12W2) beams during January - May 2016 (austral summer - early fall) at Cordón Caulle volcano (Delgado et al. 2016). U12W2 beam SAR images were acquired three days after the TOPS ones. The average coherence of the U12W2 beam is higher than the TOPS beam (see Figs. 5 and 7)
