The Brazilian one was named Mario Schenberg, a homage to the well known USP professor [ 21 ]. Detailed drawings of the whole system were prepared and two identical cryostats were custom built in the USA [ 21 ]. WebThere are two metrics for EIRP: one measured at CDF=50% and means that half of the sphere covered with required EIRP. The second one is the maximum EIRP at CDF=100%, which shows the peak EIRP value of the array. As can be seen in figure 2 both metrics are slightly different in schematic and EM calculation approaches. asahi kenntarou
