SD and Merge Auxiliary  Files 
=============================
Merge Auxiliary files are related to the merging of the three subswaths (iw1, iw2, iw3): average phase difference (rad) between subtracks estimated for each interferogram, and inverted into time series for each image, or reconstructed for each interferogram:

- list_iw23_merge_estimated_ifg.txt
- list_iw23_merge_inverted_img.txt
- list_iw23_merge_inverted_ifg.txt

Spectral diversity files give the variables used for the enhanced spectral diversity step for each subswath, before (estimated) or after (inverted) time serie inversion. phs_grad: azimth phase gradient. sx: SD gradient in range. sy: SD gradient in azimuth. syy: SD gradient inside overlap. cst: constant. sigma: standard deviation of residual SD phase.
