    v12 v13  
    1414Open '''series/civ_series''' and import the configuration from the reference file .ref. The appropriate parameters are then displayed:
    1515
    16  * mode displacement, with respect the origin index 1 (first image by default). Then the menu for choosing image pairs desappears, as the correlation for each image are done with respect to the reference one, taken as origin for the displacement.
    17  * Correlation box fairly large 31 corresponding to a coarse pattern, and considering that spatial resolution is not critical.
    18  * Large search 107 need to capture the max displacement
    19  * !!CorrSmooth =2 corresponding top carse 'particles': large correlation curves. See !TestCiv1.
    20  * Mask selected to isolate the active area
    21  * Fairly large !FieldSmooth =20 (spatial resolution not critical) and no 'deformation' needed for civ2
    22  * Civ2, same correlation box, smaller search zone as we start form  the prediction of Civ2 (shift)
     16 * Select the mode 'displacement' from the menu '''[!ListCompareMode]''', with respect the origin index 1 (first image by default). Then the menu for choosing image pairs on the right hand side desappears, as the correlation for each image are done with respect to the reference one, taken as origin for the displacement.
     17 * Choose a  fairly large correlation box, '''[CorrBox]''' =[31 31], corresponding to a coarse pattern, and considering that spatial resolution is not critical.
     18 * Chosse a large search box, '''[Search]''' =[107 107] as we need to capture the maximum displacement.
     19 * Select '''[!CorrSmooth]''' =2 which corresponds to coarse 'particles': large correlation curves. See '''[!TestCiv1]'''.
     20 * Check the '''[Mask]''' box and select the mask made previous to isolate the active area.
     21 * Chosse a fairly large '''[!FieldSmooth]''' =20 (as spatial resolution is not critical) and no 'deformation' needed for '''[CIV2]'''.
     22 * Use the same correlation box, a smaller search zone (as we start form the prediction of Civ for Shift) in '''[CIV2]''', '''FIX2]''' and '''[PATCH2]'''.
