The reason for this is unknown. This was the only experiment conducted at Madrid. Otherwise, data quality appears good throughout. The signal levels are low by about 5 dB on both S- and X-Band in the data collected on 2007/117 and 2007/122; this should not affect the science as evidenced by the MAX SNR readings on both dates. These are apocenter occultations, so the movement of the raypath through the atmosphere is slow. There is more structure during the initial decay on ingress than one normally sees; and the final decay into the noise baseline takes over 30 seconds when viewed at DSS 14. Because the equipment was still running, the RSSG captured the egress occultation on 2007/115. These are one-way data with the X-Band carrier referenced to the TCXO; but they appear to have good quality at the quick-look processing level. There was no S-Band signal on egress. Data from experiments on 2007/125 and 2007/126 were requested but not found; we have asked Gene Goltz for help in locating them.
