Regular SUSI Tasks

Web Page Updates

The master copy of these web pages is in Sydney. We can't yet set it up to
automatically copy up to arthur. So at start of each observing trip or each
week/month do:

  login to arthur as susi
  Do: /usr/bin/scp -pqrC susi@silliac:/import/www/restricted/susi/* public_html
   This will require susi password on silliac.

IERS Parameters

Go to the latest edition of the IERS Bulletin from USNO.
Scroll down to predictions. Note the 'x' 'y' and 'UT1-UTC' values for the current date.
In an arthur window do  susiedit system and enter the new values in the appropriate place.

Environment DataLogger (Easidata)

See Bill's notes re this. Data is now downloaded via the 'Theo' laptop to arthur.

Vacuum Pumps

Every two days or so pump down the vacuum in the pipes.
Take a siderostat key to the pump house.
Check: Both red 'Isolator' switches are on
       Vacuum Valve switch is on
       Vacuum Pump  switch is on
NOTE: The following order (1,2) is important. Opening the valves with the pumps off
will ingest air+dust+other crap (probably frogs;) into the vacuum pipes!
To start: 1. Toggle both Vacuum Pump switches on
          2. Open the valves. (left and right, forget the centre one)
To stop: 1. Close the valves.
         2. Toggle both Vacuum Pump switches off.
Pump down to about 0.05atm (see gauge in control room). Note S pipe gauge is faulty (apparently).
This will take 1-2 hrs, longer of course  if it's been left for a while.

Data Backups

1/ Archive in Sydney
[Edit this - APJ 070509]
Each night save data to algorab:
 eg.  scp -prC 050216 snert@algorab:susi/data
This will be replaced with an auto script...maybe...oneday...

2/ Archive on CD-ROM at SUSI
Back up data to CD-ROM regularly (~monthly).

**Do NOT do this while observing - it takes up too much cpu time!

Login as susi and cd into ~susi/data, then
 tar -czvf "output_filename" "list_of_files"

            where     c = compress
                      z = pipe the output to gzip
                      v = verbose (whats happening is printed to screen)
                      f = output filename is specified

 An example to compress directory 060224 to file 060224.tar.gz is:

  e.g.  susi@arthur: susi/data > tar -czvf 060224.tar.gz 060224

 The following should also work, but hasn't been tested:

     susi@arthur: susi/data > tar -czvf ./burn/060224.tar.gz 060224
 You could leave out v and use .tgz instead of .tar.gz if you wish.

Move the .tgz files into ~susi/data/burn/

Double-click on 'Observer's Home' icon (top left of screen)
Enter /export/susi/data/burn into location bar
Put a CD-RW into the drive on arthur 
 A window labelled 'burn:///' may appear. If not do ctrl-N for a new window
 and enter 'burn:' into its location bar
Now, drag (or copy and paste) the files from burn window to burn:/// window
 The total size in MB will sum up as you add files (a CD-ROM holds 700MB)
Click on 'Write to CD' icon. Leave the target and speed as defaults. 
 Change the name to, say, 'SUSI Data Backup, monthyy, yymmdd-yymmdd'
Click on 'write files to CD' and sit back.
When writing is done label the CD appropriately (e.g. SUSI DATA, yymmdd-yymmdd, ???MB).
Close the burn:/// window if you want to burn another CD or if finished.

Delete the now archived tar files from ~snert/data/burn/

-If the CD does not eject type eject into a terminal (You need to be 
 observer to do this)
-If nautilus (the directory window) will not display the burn:/// directory
 you will need to log out completely and log back in!
-To read a cdrom insert a cd, and do 'ls /mnt/cdrom'

Old mtar script: 
There used to be a command called mtar (Mike's tar?). But since the demise
of snert's account this no longer works.

 cd to ~susi/data and type: ../scripts/mtar 0410*

This will tar-up all directories in October 2004 into .tar.gz files
 (one file per night).
