{\bf{Afternoon Activities}}               
\begin{list}%
 {--}{\setlength{\rightmargin}{\leftmargin}}

  \item  Refill cryostat with liquid nitrogen (usually every $\sim$ 12 hrs).\\
         Check filters required and contact SA.

  \item  {\bf{COMPUTERS.}}\\ 
         Check response from TCS3210 (will give ``UI$>$'' prompt).\\            
         Check response from ICS3220 (will give ``$\ast$'' prompt).\\        
         (Computers usually left up since installation of UPS, but in case of
         difficulty consult instructions above computer consoles).

  \item  {\bf{LOGIN.}}\\                                       
         $\ast$SI XYZ,n,n \hspace{.5in} (write initials on board and
         dates resident)\\
         $\ast$ADAM \hspace{.5in} (and answer prompts: f/15;
         A\&G+CCD; GECn or EEV7; run \#)
	 To abort an ADAM command, press BREAK, type SEND CON:, couple of crs.

  \item  {\bf{FILTERS.}}\\                                                    
         If filter wheel is to be changed:\\      
         Adam$>$QWHEEL	\hspace{.5in} to choose an existing wheel; or\\
         Adam$>$WHEEL \hspace{.5in} to enter details of new wheel.\\
         Adam$>$ZEROSET \hspace{.5in} to initialise filter wheel position.
         (see III.8)\\
         N.B.  May also need to use EDITTABLE to get sensible A-G filter
         values. (III.7)

{\bf{Twilight/Evening Activities}}                                             
\begin{list}%
 {--}{\setlength{\rightmargin}{\leftmargin}}
 
  \item {\bf{TELESCOPE.}}\\ 
        Check observing floor.\\                              
        Power on.\\ 
        Oil Pump RUN. (Cancel alarm if necessary - LHS of alarm panel)\\
        Press RESET.\\
        Open dome shutters. (Hold button in)\\
        Open mirror covers. (Check not stuck)

  \item {\bf{ZEROSET AND POINTING CALIBRATIONS.}}\\ 
        In ENG mode with dome lights on.\\
	Speed knobs set to green marks.\\
        Drive telescope $\geq$3$^{\circ}$ from ZP in HA and Dec.\\
        UI$>$ZEROSET \hspace{.5in} (and hit return to begin)\\
        Drive through zenith until arrow key lights go out.\\
        Turn off dome lights.\\
        Switch to COMP mode (turn key).\\ 
        Press GUIDE to energise handset.\\
        Go to a bright star (5-6 mag).\\
        Turn TV on, wait 10s (until delay light goes out),
        turn knob to left (until it clicks) then {\it slowly} right.\\
        Adam$>$TV \hspace{.5in} (to put flat in) \\
        UI$>$SNAFU\\       
        Move star to chip centre.\\
        Press ACK button.

  \item {\bf{TAPE.}}\\
        Mount latest D tape, and record in log book in computer room.\\
        Adam$>$DATA \hspace{.5in} (and answer questions; 
        name is JKTD$\_\_\_\_$)\\
        (Maximum of 60 full size CCD frames per tape)

  \item {\bf PURGE.} \\
	To clear out disk space, use Adam PURGE command.  Not like VMS PURGE,
	  it deletes files completely! \\
        To delete protected files, use REPROTECT Rnnn/WKEY=0,189 then
          DEL Rnnn.

  \item {\bf{ENTER SOURCES / CREATE CATALOGUE.}}\\                            
        UI$>$SOU name R\_ \_ \_ D \_ \_ \_ EQ B1950\\
        etc.\\
        UI$>$SAVE MY.CAT\\
        UI$>$INPUT MY.CAT \hspace{.5in}  (on subsequent nights)\\
        UI$>$N name\\
        UI$>$GO \hspace{.5in} (to move to star NAME)
            
  \item {\bf{FLAT FIELDS.}}\\
        Go to blank sky regions. (IN BLANK at UI) \\        
        Aim for $\leq$30,000 counts/pixel. (Use GLA)\\
        Evening order: U B V R I . \\                                        
        Reverse order for morning flats.

  \item {\bf{BIAS FRAMES.}}\\
	Faster to use Adam NOPACKETS -- but after do NOPACKETS=0\\
        Adam$>$RUN 0 ``BIAS'' \hspace{.5in}  ($\sim$5-10 times, when dark)\\
        Check value with STATS mode of PHOT.  If different from default
        value, enter with BIAS command.

  \item {\bf{FOCUS.}}\\
        Go to focus star (e.g. 9-10 mag standard).\\
        Position star to left side of chip.\\
        Use GLA to check exposure time ($\geq$5s).\\
        Adam$>$FOCUS 5 15 W \hspace{.5in}  (does 5x15s; default FOCINC=0.1)
        produces image:\\
$\begin{array}{cccccc}
        f_{-0.2} &   & f_{-0.1} & f_{0.0} & f_{+0.1} & f_{+0.2}\\
        \bullet  &   & \bullet & \bullet & \bullet & \bullet\\
           1       &   &   2       &     3   &    4       &     5
\end{array}$\\
        Use PHOT or STARFIT to measure profiles.\\
        Adam$>$SETFOC f \hspace{.5in}  (best value), or\\
        Adam$>$FOCINC 0.05 \hspace{.5in} and repeat focus run (only necessary
        if seeing very good).\\
        Typical change with T is -0.05/$\deg$C.\\
        Typical value is 39.5 mm.  Start from previous night's value,
        or use chart in CCD User Guide and current tube T.\\
        (Once set, the focus tracks the tube T changes automatically.
        If there are problems with this, select Manual Focus control.)


  \item {\bf{OBSERVING.}}\\
        UI$>$N TARGET\\
        UI$>$GO\\
        Adam$>$TV \hspace{.5in}  (and position object)\\
        Adam$>$FILTER X\\
        Adam$>$RUN t ``name''\\
        Adam$>$MULTRUN n t ``name'' \hspace{.5in} 
        (for n exposures of t secs each)\\
        Adam$>$RUNSTAT \hspace{.5in}  (for elapsed time)\\
        Adam$>$PAUSE \hspace{.5in} (to pause exposure, e.g. for cloud)\\
        Adam$>$CONTINUE \hspace{.5in} (to restart a paused exposure)\\
        Adam$>$ABORT \hspace{.5in} (to abandon observation)\\
        Adam$>$STOP \hspace{.5in} (to force read-out at that time)\\
        Adam$>$TIME \hspace{.5in} (to change exposure time)\\
        (If RA button sticks, switch to INC and type\\
        UI$>$HA/I 0 \hspace{.5in} so that
        increment is zero.  Then move stars by either stopping telescope
        or with REV button.)\\       
        To trail a star across chip (for time resolved work) use\\
        UI$>$TRAIL
        or DIFF (N.B. RA differential rate must be in secs/sec, so remember
        to divide by cos$\delta$).\\
        Adam$>$DRIFT \hspace{.5in} (to use drift scan table)


  \item {\bf{DATA ANALYSIS.}}\\
        Adam$>$DISP [Rn] \hspace{.5in} (default is current frame)\\
        Adam$>$PHOT or STARFIT. \hspace{.5in} Lexidata buttons are :\\
\begin{tabular}{||l|l|l|l|l|l||}   \hline
Exit & Mode & Down & Reset & Up & BLUE \\ \hline
\end{tabular} \\
        The BLUE button is used to mark the cursor position. \\
        To redisplay image with different scaling use DIPARM. (e.g. to
           display with full 16-bit range use DIP 2 0 65535)

  \item {\bf{AUTOGUIDING.}}\\
        Power on Autoguider.\\ \\
        Adam$>$FINDSTAR \hspace{.5in}  (or see GDXY below)
		and answer questions.\\
        If no bright star visible, go to NEXT field.\\
        Move bright star to reference point.\\
        $>$ACCEPT.\\ \\
        {\bf OR} login to Vaxcluster and use Guide Star Server (instructions
           in back of CCD User Guide), then use GDXY (see below). \\ \\
        Push FIELD button, wait for star to appear.\\
        Push ACQ   button, wait for ``OK to guide'' message on
		 autoguider monitor.\\
        Push GUIDE button, wait for star to appear in circle.\\
        Push green LOOP ENABLE button (below right user i/f console).\\
        Start exposure (RUN n {\tt "name"}).\\
        N.B. A-G seeing measure is in units of 0.5 arcsecs.\\
        If star lost for some reason (e.g. cloud, as indicated by RT 
        value varying and being $\ll$1), then push LOOP DISABLE
        immediately and wait, or re-acquire.\\
        When finished, push LOOP DISABLE and WAIT buttons.\\
        If A-G ``freezes'', LOOP DISABLE, power A-G off and on, and then
        re-acquire.\\ \\
        Normal acquisition is\\
        UI$>$AC/PR \hspace{.5in} which moves the probes to find star chosen.
        This is the default when system is turned on.\\
        If guide star co-ordinates are already known, use Adam$>$GDXY, 
        then go to target
        position, and use\\
        UI$>$AC/TE \hspace{.5in}(probes are fixed, and telescope moved).

  \item {\bf{LOGBOOKS.}}\\
        JKT Direct Imaging Log (xerox at end of run).\\
        Automatic logging occurs for each RUN made. The logs are processed
           regularly and kept in a file in the control room, from which
           copies can be made, but please replace originals. \\
        Operations Log Book (e.g when liquid nitrogen filled, dome opened,
        faults, etc.)\\
        At end of night fill in Nightly Report Form.
                            
  \item {\bf{HUMIDITY AND WIND.}}\\
        If $>$50\% humidity in dome, turn on dry N$_{2}$ to first notch.
        Turn OFF at end of night.\\
        If $>$90\% outside, close down and wait until $<$80\%, or conditions
	 stabilise.\\
        Wind speed limit for JKT is 50 km/h (steady, not gusts).  If
        concerned, check with INT T.O.

  \item {\bf{COPYING DATA.}}\\
        Fill in Tape Copy Request Form and place in tray with D tape for
        D.O. to collect.  C tape will appear in INT Visitors' pigeon hole.\\
        D.I.Y.:\\
        Adam$>$FITSINIT \hspace{.5in} (JKTD\_\_\_) for first time use\\
        Adam$>$FITSOUT \hspace{.5in} (e.g. R1-R60)\\
        Please complete a Tape Copy Request Form even if copying data
           yourself!

  \item	{\bf Problems.} \\
	You won't have any problems you can't solve yourself, but just
	  in case, go F-7-9 on intercom, hold down SIMP, ask for your
	  support astronomer first, if not available then for the
	  duty tech (usually before 11.00pm). \\
        Report {\bf ALL} faults in the Defect Database, held on LPVS3, 
          username FAULT.
