Open Loop Data ============== We have completed quick-look processing on the following MEX RSR open loop radio occultation data at Stanford.

The signal remained well within the pasband, however, so there should be no impact on science. On day 017 there was no noticeable drift, suggesting that the drift resulted from use of an older orbit prediction. On day 016 there was an odd spike in X-Band signal amplitude about 10 minutes after occultation and just before the antenna apparently went to zenith. There was a similar anomaly on S-Band. Since both are well after occultation, there should be no impact on science. Data from day 017 appear to be nominal.
