Got deeply involved in calculating Dopplers for Arecibo for tomorrow. Think that's in good shape; at least the algorithm checks against the screen dumps we collected last weekend. When you have a chance, could you FAX me a copy of your real time notes from today? No rush, as I probably won't have a chance to do anything with them until I return from my trip late next week. The FAX is 650-723-9251. Make sure the FAX is clearly addressed to me; 150 people share that machine, so it's easy to lose incoming messages if they can't easily be directed.

Mpack/munpack is available via anonymous FTP in ftp.andrew.cmu.edu:pub/mpack/ --- Gene: This is my recommendation for the MEX bistatic radar operation tomorrow (Friday) morning. It will be very similar to what we did last Sunday. If 63 is on point 10 minutes early, we could catch the egress occultation -- at least on S-Band. Both transmitters go off at the end of the BSR, so you won't have to wait for the spacecraft to return to Earth point. The detailed processing at Stanford shows a surface echo present for more than 20 minutes in X-LCP rather than just the 5-6 we saw in real-time Sunday. There may be something present in X-RCP and S-LCP; haven't finished squeezing yet. Only one that looks empty so far is S-RCP, and that was the least likely. So the experiment is working; we just have weak echoes. I'll plan to be near the phone in the lab at Stanford (650-723-0296) -- planning the experiment for day 098.

There were two prob- lems encountered during the pre-cal procedure: 1. when Step #2 was performed, at ~15:48, all of the ADC values went up to just below zero (e.g., -0.n) -- only the two X-band values should have changed in that way -- as if Steps #2, #3, and #4 were all done at the same time; Jesse checked the station's OCIs, and found that a zero had been entered in place of the letter "O" in one of the input directives; we restarted the pre-cal procedure from Step #1 at 15:58 2. there was an unexpected increase in the X-band LCP ADC value at Step #8, but another increase was seen (as expected) when Step #8 was ex- cuted; Jesse found no errors in the station OCIs, and we did not try to repeat any of the earlier steps. Otherwise, everything went well -- but, as expected, any signal was very difficult to discern in the FFTs. - Gene --=====================_1057688046==_ Content-Type: application/octet-stream; name="MEX_BSR_2006097.xls"; x-mac-type="584C5334"; x-mac-creator="5843454C" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="MEX_BSR_2006097.xls" 0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAPgADAP7/CQAGAAAAAAAAAAAAAAABAAAAOgAAAAAAAAAA EAAA/v///wAAAAD+////AAAAADkAAAD///////////////////////////////////////////// ...

Your responses make sense; sometimes we can only unravel the station performance by looking at the data (in conjunction with the NMC log). I'll let you know if anything might have been changed based on the data examination.
