Unfortunately, the revised report was distributed with the NOTE in the label indicating that is was HEA4245B.TXT. In fact, the NOTE should have said HEA4244B.TXT.

This is additional data, beyond what he reported in HEA4237A.TXT. I have investigated the frequency stability of a number of open-loop RSR recordings from 2004/231. The DOY 231 recordings were acquired simultaneously using RSR1 with upgraded software and RSR2 with existing software over passes at DSS 34, 55, 25 and 26. A total of 11 ingress occultations were recorded in tandem. I selected one pair of recordings from each pass for investigation. Earlier results of quick look processing for the two sets of recordings were essentially indistinguishable. That conclusion may now be extended to estimates of USO frequency and Allan Deviation from more sophisticated analyses. I used the latest NAV trajectory reconstruction (spk_m_040815_OD24301- 24395_rec_V1) to make the Allan deviation computations for the DOY 231 recordings. The results may be found in the tables below. There was no difference between the weighted USO frequency estimate from each RSR for any of the occultations. Based on that and the measurements of Allan Deviation, I see no significant difference between the performance of the RSR's with existing and upgraded software on this date. There was no appreciable difference in stability between the two RSR's at any integration time for any of the occultations. Furthermore, the small differences in stability do not seem to consistently favor one RSR over the other.
