| 250 | | -'''Error flags''': they mark in magenta color vectors considered as false. These vectors are kept in the data set so that their elimination can be reversed, but they must not be taken into account for data processing. They can be removed for visualisation by selecting the check box '''[!CheckHideFalse]'''. |

The red values correspond to poor correlations, green to fair values, and blue to good ones. The value range covered by each of the three colors is set by the pair of sliders '''[Slider1]''' and '''[Slider2]''', or equivalently by the edit boxes '''[num_ColCode1]''' and '''[num_ColCode2]'''. Other color representations can be specified.

| | 250 | -'''Error flags''': they mark vectors considered as false. These vectors are kept in the data set so that their elimination can be reversed, but they must not be taken into account for data processing. These false vectors are displayed in magenta. They can be also removed from the plot by selecting the check box '''[!CheckHideFalse]'''. |

| 259 | | -'''Mouse display''': when the mouse is moved over a vector, it is marked by a circle, and its features appear in the display text boxes on the upper right. These are -* fist line: the position coordinates x, y, (z for 3D cases). -* second line: the vector components -* third line: the vector index in the file, the values of the scalar (C), the warning flag (F) and the error flag (FF). The meaning of the flag values is given in [section 10.3->#sec10.3]. |
| 260 | | |
| 261 | | -'''Manual editing of vectors''': vectors can be manually set as 'false' by pressing '''[!Edit/Vectors] ''' in the menu bar, then selecting the vector with the mouse. The selected vector becomes magenta. Inversely, if a magenta vector is selected, it is rehabilitated and retrieves its initial color. The corrections are recorded as false flags in the data file by pressing the pushbutton '''[record]'''. |

| | 265 | -'''Manual editing of vectors''': error flags are automatically produced by the PIV operation, see [#a11.3FIX section 11.3]. It is also possible to introduce them manually by checking '''[edit_vect]''' and selecting a vector with the mouse. The flag can be removed by selecting it again. To record the changes in the input file, press the button '''[record]'''. |
