When entering Identification section user should open the file with observed positions of objects which are to be identified (the file may be first created). As this takes place, user's actions do not vary from those described in IV.2.List of observations It should be taken in mind that the type extension which is actual in default of specifications is “.idn” (identification). The only possible extension permitted for the new name of the file with observations are “.idn”.
In the wake of file opening its content is displayed.
It is supposed that file contains astrometric positions in right ascension and declination with respect to equator and equinox of 2000.0 (the other possibilities are of little interest and therefore are not considered). The data of each observation are written in one row. Format of observations must coincide with that of optic observations in which they are published by Minor Planet Center (observed position may be presented as “accurate” or “approximate” one):
| Columns | Use |
| 1–13 | object designation — any combination of symbols |
| 16–31 | date of observation (UT) |
| 33–43 | observed right ascension (in hours, minutes, and seconds of time (“accurate position”) or in hours and minutes (“approximate position”) |
| 45–55 | observed declination (in degrees, minutes, and seconds of arc (“accurate position”) or in degrees and minutes (“approximate position”) |
| 66–71 | observed magnitude and, optionally, band |
| 78–80 | observatory code |
Content of other columns does not influence on the identification process.
