Example of growth curves acquired with a continuous exposure time of 0.13 seconds per frame, under moderate sky condition (see values in the text). The position of the stars may be found in the sky field of Figure 1 reading the the Tycho-2 identification number (id number) labeled in -axis. For each star are reported the values of the ellipticity, the FWHM using as best fit a Moffat profile, and the pixel coordinates.
