You can find the main guidance’s characteristics of constellation’s identification on the frame and astrometric/photometric reduction choosing Settings/Parameters/Astrometry (Fig. 2.8). Following settings are available:

- camera rotation angle (field camera rotation [deg]);

- minimal apparent brightness of stars used for identification of magnitude (field magn.threshold (diurn.));

- size of the area downloaded from the catalog for constellations’ identification (field Stars search +/- FOV);

- settings of rough/precise identification on the matching boards.

You can also choose stellar catalog for astrometric (Additionally/catalogue(astrometry)) and photometric (Additionally/catalogue(photometry)) reduction.

The model of plate constants used at the astrometric reduction can be found on the board model.
