During the fifth track (!), the strategy will be to get a
CW detection and then move to coarse resolution ranging as
soon as possible.  Then we'll devote the rest of the track to
0.5 us x 0.075 Hz imaging.

Starting CW setup for the fourth track:

RCV polarization          LCP

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.

BEGIN ELECTRONIC LOG

Present: Benner, Jurgens, Rose, Franck, Kelley, Jao, Ostro remote on east coast

Joseph arrived with a recently repaired exabyte tape drive, a new keyboard, 
and tapes.  He wants to test fixes to the ACSM software (originally a problem
dating back to April).  In the event that the software fails, he says it will
take only a couple of minutes to switch back to the old software.  

1633: We're ready.  

Using Solution 21


TX Power = 440 kW for CW

 TX  polarization             RCP
 RCV polarization             1=RCP=OC=15.14 K at zenith
                              2=LCP=SC=16.07 K at zenith


Ch 1 Tsys =  17.14 on point (39.8 deg el)
Ch 2      =  17.91

Starting CW setup:
TX  polarization              RCP
 RCV polarization             both
 Frequencies:                 2
 Dwell:                       30 seconds
 Bandwidth:                   1000 Hz
 Sampling interval:           10000 x 0.1 usec
 VME FFT for PSD files:       4096 for 0.244-Hz resolution

165513: beam is up
ACSM software problem.  Restart with old version.

165712: beam is back up

1659: no levels..

Strong echoes.  Doppler corr'n = +0.5 +/-0.3 Hz
                bandwidth has increased: ~2.4 Hz

Delay drift = (0.42 us/h)(0.5 Hz) = 0.21 us/H.  So we might get 
about 1 gate of drift if we do 2 h of high-res imaging.  


Configure for 10 usec
=====================
127 x 64 10-usec single sample

baud            10 usec
code            127
gates           127

CLT             11

resolution      2.46 Hz
TXOFF           +25 Hz
incoh sums       =>  sec/record

loopback: OK
cold sky: OK

1712: loaded wrong setup--6.15 Hz res'n, not 2.46 Hz.  Load correct one...

cold: sky OK
loopback: ok

172400: beam is up

Echo.  Very strong.  Extends over 2 range gates

Change display---gates 9 & 10, even some echo in gate 11.

No hardcopy of the 10 us echo!  HP printer not printing...Joseph and
Richard were trying to set the printer back on the network during the
observations!  they accidentally took it offline. OK...it's back.  All
the hardcopies are printing.  

LE is in gate 9.  Adopt COM = LE + 2 gates 



Configure for 11 usec
=====================
127 x 64 11-usec single sample.

baud            11 usec
code            127
gates           127
PRP             1397
FFT             64
CLT             11
ncoh            5
bandwidth       143.16 Hz   
resolution      2.236 Hz
TXOFF           + 22 Hz --> put echo about 10 Doppler cells over

loopback: OK
cold sky: OK

174216: beam is up

Echo in gates 9-11--> So range is very good.  We're about 20 us early




Configure for 0.5 us x 0.075 Hz
===============================
setup             
baud            0.5 usec
code            255
gates           255
FFT             256
ncoh            409
bandwidth       19.18 Hz     
resolution      0.075 Hz
TXOFF           +4 Hz, +25 us = 53.3 cells
incoh sums      xxx looks=> xxx sec/record 
CLT gate        17

txoff = +4 Hz, + 50 gates (so echo doesn't split in range)

loopback: OK
cold sky: DC...Carl is removing it...OK

1804: Echo!  Appearance has changed again.  Delay-Doppler parabola is
more symmetric than yesterday.  See a group of points near the negative 
trailing edge.  More echo power on + edge.  

visible delay extent is about 45 gates = about 22 usec.

See another line of bright points in constant delay extending across
the image.  It's about 8-9 us in from the LE.

SNR is about 115 in the strongest pixel

1827: cleared the display.  

1837: acsm problem...OK.  up to run 16

1849: up to run 20.  clearing display every 10 runs. 

1908: Joseph swapped the tape drive.  We're now backing up the data from all
the previous tracks onto 1999JM8_072399_1.1, which I was unable to do after the
previous track.  Unfortunately the power to the Mac, the printer, and the Suns
went down when Joseph bumped one of the power strips with his foot.  The cabling
behind intruder and aardvark is clearly not safe.  Everything is back up.  
The datataking was not affected.

1913: the "line" of stronger points at constant delay isn't so obvious now.
The collection of points on the negative edge near the limb is still evident.

1933: tape backups work again.

1956: there is another arcuate feature the separates from the "line" and is 
roughly parallel with the positive edge, but is a few tenths of a Hz negative
relative to that edge.  I didn't see this in earlier images.   We have enough
runs and SNR today to make a decent movie with several panels.

2013: nearly done.  Just discovered that we haven't recorded for about 13 minutes.
Something with th AC...  last known draw was at 195954.  It's not clear what
the problem is.

last 7 runs may not have any data.

PROBLEMS
========
1. Bad cabling behind aardvark, stealth, and the printer.  it's dangerous because
a slight bump can bring down the computers.

2. Joseph's fix to the ac didn't work.  It wasn't a problem for observing, though--
it cost us only a couple of minutes.  

3. HP printer still isn't on the network.  Can print from Suns w/low-level command.
Joseph and Richard tried to fix it...unfortunately, right as we were starting 
ranging when we needed to make copies.  

4. Stopped recording data during the last 15 minutes of the track.  Not yet clear
why.  Something wrong with the AC software?  


Things to do before leaving

Draft critique
==============
Good track.  Images are outstanding and will provide powerful leverage to 
reconstruct the asteroid's 3-D shape.
