This is because some hardware switch will take place early next week that will affect RSR2 (the current RSR2 will be switched to a VSR (VLBI RSR), and a new RSR2 rack will be installed). The notifications will show RSR1 starting with tonight's DSS-34 pass. The notifications for SPC-10 will continue to show RSR2 (the switch has already been made at SPC-10, but that affected RSR3).

We can monitor the timing of the rewind but otherwise save some effort in collecting, transferring, processing, and archiving data. But this is a great opportunity to gather egress measurements, which are so scarce in beta supplement mode. I've also appended an e-mail from Bill Adams that Aseel distributed on September 23. We should firm up the dates if possible. Will egress be affected? Message from Dick Simpson: > > Would it be worth cutting back on the ingress measurements > until the HGA is out of the way again?

Therefore, I would collect all the ingresses and egresses as I normally would, and then I'd edit the notifications that get sent to you so that only one notification per day includes an ingress measurement. I can start doing this on DOY 276. There are three passes on that day: DSS-25, -43, and -63. I will remove all the ingress measurements from the notification for DSS-25 and -63, and leave one mid-pass ingress measurement in the DSS-43 notification.

Can you please >confirm that the problem is gone. The bad DSS 63 spurs reported for the 273/274 pass had been cleared up by the 275/276 pass. So there were only two really bad days. 63 may have the distinction, however, of the worst spurs outside of those two days. In the plots for 20455e I can see spurs at +/-50, 60, 180, and 300 Hz. The picture is similar both before 273 and since 276. This is not intended to be a new alarm, just an observation.
