Sometimes there could be objects left unidentified by the program but identified be the operator. In order not to loose such objects the program has a special function of tracks’ formation by the operator. For its activation you have to:

- turn off the blinking;

- using the mouse, place a chosen part of the frame in the center of the window magnifying glass and push the combination of keys Shift + left mouse button.

As a result, you will see the tab of tracks’ formation in the tracks’ window (Fig. 2.16). There you can choose a method of receiving objects’ coordinates on the specified frame: to take coordinates of a mark (if there is such mark) or to evaluate coordinates around the nearest peak. You can also choose a name for the present track in the same tab. The name has to be composed of seven/eight symbols. The coordinates of the object can be indicated in a new track through accept.

Then you can pass to the next frame and see the next display of the specified object. Attention! When you receive coordinates of the specified object’s marks on the different frames, the name of the track has to remain unchanged.
