    v177 v178  
    776776
    777777 * '''PIV''': makes image comparisons on sliding index pairs, as usual for measuring velocities by particle displacements. A second menu '''[!ListPairMode]''' in the panel '''[!PairIndices]''' then selects one among three possibilities (not always available depending on the file indexing):
    778    * ''pair j1-j2:'' selects a given j index pair (sometimes denoted by letter index) for the whole time series. This is the most common case for PIV. Pair selection is performed in the menu '''[!ListPairCiv1]''' and '''[!ListPairCiv2]''' for the second iteration Civ2, see below. If timing from an XML file [#a3.5Imagedocumentationfiles.xml <ImaDoc>] has been detected, this is indicated in the edit box '''[!ImaDoc]''' and the corresponding time intervals are indicated (in ms). For some applications, this time interval may evolve in time, so that reference indices ref_i and ref_j are chosen for the display.

    779779   * series (Di): selects a given  index interval for the i index, around a set of reference i indices. The intervals are denoted Di=0|1, -1|1, -1|2, -2|2 ... , corresponding to the index pairs i|i+1, i-1|i+1, i-1|i+2, i-2|i+2 ...around each reference index i. Pair selection is then performed in the menu '''[!ListPairCiv1]''' and '''[!ListPairCiv2]''' like for 'pair j1-j2'.
    780780   * series (Dj): same as series (Di) but with the j index.
