V.4. Running the calculations

To start identification process mark one observation or some group of observations in adjacent lines by sliding bar (to do this move the mouse with the left button pressed or keep Shift key pressed and extend selection by use Up and Down arrows, Page Up and Page Down keys). Subsequent identification will be fulfilled for marked observations. Identification will be fulfilled for all observations in the file unless preliminary marking is done.

To run calculation, select Identify item in drop-down menu. Then in Tolerance dialog box place limits on allowable departure of observed position from computed one in right ascension and in declination. The default value of the limit is placed to be 30 arcsec both in right ascension and declination.
