Lunar Radiometric Measurement Based on Observing China Chang’E-3 Lander with VLBI—First Insight

Figure 9

X-band SNR of reference quasar of all baselines in OCEL09. (In this case, 4 channels corresponding to DOR tones channel are used for bandwidth synthesis. Though designed SNR value is 35dB, SNR from 7dB to 15dB takes up nearly 40%, and most of lower SNR observables come from baselines combined with station FORTLEZA.)
