Hi, Dave.  This is a note to bring you up to date on my plans for
Eureka this winter.

1) I sent a package to Edmonton yesterday morning, for forwarding
to Resolute and Eureka.  With luck, it's in Eureka now.  The
package contents are as follows:

- new Polar Camera log book, containing various information sheets
  pertaining to the instrument and its operation:
  - installation instructions for Albert,
  - routine operations,
  - calibration,
  - changing calibration source batteries,
  - a listing of the files on a floppy in the package;

- 3.5" floppy disk containing files to be installed on the Polar
  Camera hard disk, and installation and operating-mode modification
  batch programs

- print-out of the READ.ME file from the floppy disk (see below)

- padded envelope containing the Polar Camera watchdog timer and
  a box of spare fuses for the timer

With this letter I'm enclosing a 3.5" floppy that contains all the
listings in the package, plus a few more that didn't get written in
time.

The instructions for Albert need to be slightly augmented, as
follows (I was in a rush on Tuesday night):
- ASAP after arriving at ASTRO, please install the "shorting plug"
  in the Polar Camera PC (per instructions in package), and power
  the PC up via the voltage-regulated power bar;
- watch for "unusual behaviour", i.e., smoke, melting plastic,
  unstable operation like spontaneous power cycling;
- the following day, connect the PC per the "final configuration"
  diagram in the instructions, bringing the watchdog timer into
  the circuit and connecting the data cable between the timer and
  the backplane of the PC, and installing and cabling the cameras;
- after booting the PC, install the files on the floppy in the 
  package per the instructions in the READ.ME file, run the batch 
  programs MAN.BAT, BIN2X2.BAT, and NOQLOOK.BAT, and then leave the 
  system sitting at the DOS prompt;
- after several hours to a day, come back and check the contents
  of the C:\IMAGES\LOG\BOOTLOG.??? file(s) to see whether the watchdog
  timer rebooted the system - dates/times of system bootup will be
  recorded there;
- if the system is running a program when you check, the watchdog 
  timer has rebooted the system;

I have sent a modified version of the camera control program that
ran last winter.  The new version *should* allow acquisition of
smaller-format images, thereby allowing a considerable saving of
disk and tape space.  However, I don't want to start that program
until the person on site has time to check that it is performing
as expected, i.e., until Greg's tour begins, and I can't generate
a complete tape change schedule until I know whether the small-format
program is working.  Therefore, I can only specify the first three
tape change dates, as follows:

  As soon as normal PoCa operation starts, insert tape EU9342.

  On or about October 25, preferably after the backup at 18:00 UT, 
  remove EU9342 and insert EU9343.

  As late as possible before Albert leaves Eureka, remove EU9343
  and insert EU9344.

  As soon as possible after Greg reaches Eureka, remove EU9344 and
  insert EU9345.

I am enclosing daily log sheets for recording Polar Camera statuses,
exactly like those used last winter.  The five sheets enclosed
should be adequate for the winter.

In addition to making smaller-format images, the new camera control
program *should* allow creation of quick-look data files, showing 
average zenith count rates for each image acquired by the system.  
From time to time, I will request the on-site operator to transfer 
a compressed quick-look file down to CANSAS via e-mail, as was done 
last winter with temperature logs on cold days.  The enclosed floppy 
disk contains a DOS batch program, ZIPQLOOK.BAT, to generate the 
compressed quick-look file and write it on a floppy.  Please ask 
Albert to copy the program to C:\BATCH on the Polar Camera control PC.

I've also written a batch program, ZIPBKLOG.BAT on the enclosed floppy,
to compress a backup log generated by the backup utility on the PoCa PC.  
I need to look at this to see how much of a space saving is produced by 
acquiring small-format images.  If Albert can copy ZIPBKLOG.BAT to 
C:\BATCH, then once Greg gets to Eureka, I'll request through you that 
he run the backup log batch program and e-mail the results down.

I hope that's all I need to send you.  If you have any questions, please
let me know.  Thanks for all your help.  I pray that you will be given 
light on the path you are to follow (see Psalm 119, verse 105).

With best regards,

Dave
