I have processed each open-loop recording, and the results may be found in the tables below. The USO frequency extracted from the recordings at stations 24 and 25 agreed to within 1 mHz for each occultation (Table 1). The SNR for each occultation was better at DSS 25 than DSS 24, the difference ranging from approximately 0.7 to 2 dB (Table 2). The frequency stability at DSS 25 was better than DSS 24 at integration times less than or equal to 4 seconds (the short integration times are those most affected by SNR); at integration times greater than or equal to 8 seconds the stability at station 24 was generally (except in one case) comparable or better than that at 25 (Table 3).
