Figure

Fig. 1. Event at 22:19:06, 20 February 2001, compared against the catalogue. The top panel shows a quantity proportional to the signal to noise power ratio
Figure 2 shows the distribution of object diameter, as determined by the analysis of the reflected signal amplitude, as well as the prediction by the MASTER/PROOF’99 model
Fig. 3. Distribution of orbital altitudes. The prediction of the absolute object number as a function of orbital altitude by the MASTER/PROOF’99 model is shown as the gray histogram
Fig. 4. Mapping of orbital inclination to Doppler velocity for a southern antenna pointing.
