Attached are plots of the lab- and sky-calibrated Tcal values for our X-band receivers. Four antennas were out of the array at the time of measurement, and will have to be observed later. The black traces are the lab-values, the red are the sky-values. </div>

A few antennas, especially ea05, with receiver #10, show what looks like a large standing wave — in both the lab and sky values. The period of about 1 GHz suggests a reflection separation of about 15cm (free space). </div>
