    Dear Prof.Daniele

    I make APS processing ,the Delaunay connection result looks well,but the PS coherence after Graph Inversion and APS remove is very bad. Can you tell me the reason about the bad PS coherence ? And what can I do for have a good result?
    Thank you !

    probably you used wrong weights.
    which APS options are you using?
    Can you grab the APS module screen and show them to us?
    Also, how many images are you processing, from which sensor, which images graph?

      I use 18 images,they are TSX and TDX . The images Graph is STAR,1 sensor.
      The attachment is APS module.

    1) why do you use DS=10 and DL=10?
    Leave DL=0.
    2) how big is the area, did you check the initial selection of points in the refl map/amp stab map?
    18 images is enough for a PS-like analysis, but you have to be very careful because all statistical indexes are affected by the low number of images.
    3) why didn’t you keep the Non-Linear weights suggested by the sarproz? in any case, lowering the lower threshold as you did is not a good idea. you could use .9 .95 and 1
    4) it’s useful also to look at the colored connections to see how the graph looks like
