MKIV COMMENT: Sun Oct  3 17:35:48 GMT 1999
Major software update today:
Data are sent to the host, nahenahe, while the next scan is beginning.
Turn around overhead was about 50 seconds with old code and mkiii,
33 seconds with old code and mkiv, and is not 13 seconds.
Kcc is now synchronized to the mkiv, not the mkiii, or a surrogate
the last couple of days.  Look for a change in the number of 

'bad' reads as a consequence.  Also pay close attention to the headers
as they are produced at each scan position rather that all at once
at the beginning with only scan varying fields filed at each scan.
This was necessary so that the data write/collection could be overlapped.
There are now raw detector dump data at the end of each file!  These
consist of 8 reads of P channel which has 768 pixels followed by
8 reads of the S channel which also has 768 pixels.  P is in inverse
order with respect to height.  

Bias level is measured at the first 32 pixels at the beginning of every
scan.  If the level is not zero, bias at all heights are multiplied
by the change need to zero the bias.  Watch these first pixels in the
data to make sure this is working.
MKIV COMMENT: Sun Oct  3 17:49:47 GMT 1999
Correct performed followed by a cal.  Let us hope clouds stay away
so we can run a sequence.
MKIV COMMENT: Sun Oct  3 17:50:56 GMT 1999
More on software.  The synchronization to MkIV now means a slight
change in the number of scan azimuths.  I suspect is starts and
ends more punctually with the same azimuth increment in between.
Expect 982+/- records in the new data.
MKIV COMMENT: Sun Oct  3 17:52:52 GMT 1999
Lots of fine coronal structure visible near the limb.  The prominence
cavity at 170 shows several loops.  The AR at 220 has funny looking
spikey things (how scientific!).

MKIV COMMENT: Sun Oct  3 18:13:29 GMT 1999
The gif images show a rock steady intensity vs time.  This means that
we have fixed the intensity drift so that the sky transmission works
correctly for adjusting the intensity.  Now...what algorythm is
being used to correct for sky transmission?

Something funny with 18_34 scan.  Q is far too large for most of the scan.

Even with the mirror gain set down to -5 there are still fuzzy images
being taken for the flat field sequences for all 3 wavelengths.  The top
row of images are always fuzzy, I recorded the quadcell stage positions
for those images for future reference.  Once I can get manual images
displayed I can experiment more easily with those quadcell stage
positions and the software gains and other things.  We may have to
realign the optics to avoid those stage and fast-mirror position
combinations.

Regarding the use of the ephemeris for pointing, it looks like the
ephemeris is used after every time the images are written to disk,
but it doesn't need to be, in fact when it is used it points the 
telescope farther away from the sun than if the tracking mode were
used.  It may be that the guider servo and the mirror servo don't
need to be turned off at those times, because they are turned back on
within a few seconds.  If they need to be turned off then it would be
better to leave the telescope in tracking (clock-drive) mode then turn
those servos back on (guider then mirror) without using the ephemeris.
That would save a lot of time and prevent problems throughout the
day.  I've left the telescope in tracking mode for over an hour and the
solar image stayed on the quadcell the whole time, that's all we need 
between sequences that make use of the servo loops for the images.
I'll talk to Randy about modifying the software. -Darryl

I setup the automatic dome rotation again since it is about the right
time of the year for it.

WEATHER COMMENT: Sun Oct  3 20:47:50 GMT 1999
Orographic clouds are starting to pass over.
**PSPT PROBLEM**: Sun Oct  3 20:48:11 GMT 1999
During the 2000 ut sequence the images looked fuzzy so I tried changing
the mirror gain while Kim and I watched the error meter needles.  We found
that the best setting was at -15, instead of -5 where I had it.  So I 
changed the code and tried to startup using Restart but it wouldn't due to
lack of diskspace due to the data tape not being completed last night.
Obs doesn't work so there is no way for me to transfer data or write a
data tape or take data, no way I know anyway.  I'll keep trying things.

Today we ran a sequence of Calibrations.  Unless superceeded by a better
set Monday or Tuesday, this is the set of MkIV cals to use to examine
stability of Gain, Offset, an the X matrix elements throughout a morning.
WEATHER COMMENT: Sun Oct  3 21:44:59 GMT 1999
Right on the edge of the dissipating cumulus.  This calibration may therefore
not be as good as one would like.
