H = 15 ==> diameter = 3.1 km; assume period = 12 days (!), equatorial view, radar albedo
= 0.1.  Assume optimal parameters for Goldstone and Tsys = 31 K, sensitivity = 7.3 K/Jy
for Arecibo.  Tracks in bold are those scheduled for observations, where the times

Ray Jurgens and Carl Franck have added 3 new configurations that
provide range over-sampling.  The original long baud configurations
are set up as follows:

Config.    baud   over  range   FFT     coh     BW      Res
           micro  samp  gates   freqs   sums    Hz      Hz
           sec

JX1XS0700   7.0     1   127     64      3       375     5.86
JX1XS1000  10.0     1   127     64      2       394     6.15
JX1XS1100  11.0     1   127     64      2       358     5.59

We added the following to the JX set:

JX1XS0350   7.0     2   254     64      3       375     5.86
JX1XS0500  10.0     2   254     64      2       394     6.15
JX1XS0550  11.0     2   254     64      2       358     5.59

These new configurations have exactly the same coverage in range
and Doppler frequency as the previus set.  They provide 2 range samples
per baud filling in the deep hole between gates in the original set.  The
only disadvantages in using these are that they record more data in a 
given amount of time for the same amount of integration, and the display
is crowded if you try to show all gates at one time.  

SNR tests using the these are essentially identical to the originals.

 Sampling interval:           10000 x 0.1 usec
 VME FFT for PSD files:       4096 for 0.244-Hz resolution

CW objective: verify that we have echoes, then go to high res imaging
using the 1 us x 0.1 Hz Toutatis setup 

033529: beam is up.  See echoe on first draw.  Very strong.
Bandwidth is about 2 Hz, Doppler offset about +0.1 +/- 0.2 Hz.

0045: Mac display locked up before loopback printed.  Gate is 17.
Restart the Mac... OK.

lb and cold sky OK.  Got hardcopies.  5 Hz txoff was a bit much.  3 Hz better.

005146: beam is up

More Mac display problems: threshold too low, taking too long to show
all 255 x 256 points.  Echo near gate 250.  Insert txoffset of +50 gates
or + 25 usec. 

Echo has drifted down in delay, as expected given yesterday's Doppler
corr'n of +0.8 Hz.

change display: gates 20-90, bins 140-240.  zoom in.

0136: nearly done.  going smoothly.  Strongest edge has shifted from
positive Dopplers yesterday to negative today.  Curious because if
P = 14 days, then the rotation is only a couple of degrees.

0140: end of track.  Got 44 sums.

PROBLEMS
========
1. We were a bit slow in starting.
2. Macintosh display locked.  Restarted it.



Things to do before leaving
===========================
1. transfer ranging data -> intruder then ftp to JPL 	==> IN PROGRESS
2. transfer cw data      -> intruder then ftp to JPL	==> DONE
3. transfer tx/rcv logs to intruder and then to JPL	==> DONE
4. write protect all data and log files	at JPL		==> 
5. update website on reason				==> 
6. set up log file for tomorrow				==> 
7. critique 						==> DONE
8. get the data package					==> 
9. back up the data ->  exabyte tape & write protect it	==> 
10.organize hardcopies  				==> 
11.ftp observational log -> JPL and write protect it	==> 
12.e-mail brief summary of results -> co-authors        ==> 
13.e-mail brief summary -> Ralph & Larry                ==> 

Draft critique
==============

Good track.  Everything went smoothly.  Interesting surface features.
