OPERATIONS INSTRUCTIONS FOR THE 0.9m TELESCOPE
-------------------------------------------------------------------------

I. STARTING UP

YOU SHOULD GO UP TO THE TELESCOPE AT AROUND 3PM TO START CALIBRATIONS.

LOG INTO COMPUTERS IF THE ASSISTANT HASN'T DONE SO ALREADY:
	LOGIN: V12
	PASSWORD: 34hSt46

LOAD CTIOPI PACKAGE BY TYPING ctiopi TO USE COMMANDS SUCH AS qlook, ETC.

CREATE A DIRECTORY FOR THE DATA WITH THE NAME BEING THE BEGINNING OF THE 
	NIGHT OBSERVING, ie, 0707-09 (YOU WILL HAVE TO RENAME THIS DIRECTORY
	AT THE END OF THE NIGHT).

CD INTO THAT DIRECTORY IN BOTH WINDOWS (THE ARCON ACQUISITION & THE ARCON
	REDUCTION)

TYPE epar obspars IN THE BLUE ARCON WINDOW TO RE-SET THE FRAME NUMBERS
	TO f001 FOR THE BEGINNING OF THE NIGHT. ALSO, MAKE SURE THAT THE
	OBSERVERS ARE THE CORRECT NAMES.

TYPE preview 1 THREE TIMES TO FLUSH THE CCD CHIP FOR THE START OF THE NIGHT.

GO UP TO THE 'SCOPE AND PUSH IN THE TWO DARK SLIDES.

II. FLATS
NOW YOU ARE READY TO TAKE THE BIAS FRAMES.
TO DO THIS, TYPE
	observe/zero/17/bias

CHECK THE COUNTS ON THESE FRAMES. TO DO THIS, TYPE imstat f001 IN THE 
	REDUCTION WINDOW. THEY'LL BE THE MEAN.  THE COUNTS SHOULD BE BETWEEN 
	500 & 600. q TO QUIT.

WHEN THE BIASES ARE DONE, TURN ON THE DOME FLAT LIGHTS. THEN, UPSTAIRS TO 
	MAKE SURE ALL THREE LAMPS ARE ON. PULL OUT THE TWO DARK SLIDES.

NOW YOU ARE READY TO TAKE THE DOME FLATS. TO DO THIS, TYPE
	doobs/11/dflats/cb/v,r,i/160

CHECK THE COUNTS ON THE FIRST FLAT FRAME TO BE SURE EVERYTHING IS WORKING OK.
	THE COUNTS SHOULD BE 35K, 30K, & 25K RESPECTIVELY FOR V,R,I. DO THIS
	BY TYPING imstat f020, ETC.


NOW YOU CAN GO TO DINNER!


III. FOCUS
WHEN YOU COME BACK, MAKE SURE THE DOME LIGHTS ARE OFF. PROBABLY THE ASST. WILL
	HAVE TURNED THEM OFF ALREADY & OPENED THE DOME.

MAKE SURE THAT THE UTs ARE SYNCHED (ON THE TCS & THE DISPLAY PANEL ABOVE THE
	GUIDER). TO DO THIS, CLICK ON TELESCOPE/INITIALIZATION. THEN ENTER 
	CORRECT TIME (AND APPLY).

MAKE SURE THAT ON THE TCS BLACK BOX 'TRACK', 'DRIVES', 'AUTO DOME', 'AUX TRACK'
	& 'DOME TRACK' ARE SWITCHED ON.

THEN, GO TO A BRIGHT STAR (OR YOUR FIRST OBJECT) TO CHECK YOUR FOCUS. THERE 
	ARE ALREADY SOME IN THE TCS PROGRAM FOUND UNDER TELESCOPE/MARK-MOVE 
	TABLE. SLEW TO THIS OBJECT TO CHECK YOUR FOCUS. THERE ARE TWO WAYS TO 
	DO THIS:
	1) USE THE IRAF focus COMMAND, CHOOSING 10 SEC. INTEGRATIONS WITH A 
		FOCUS INCREMENT OF 50. THIS WILL GIVE YOU 7 FRAMES FROM 
		WHICH YOU CHOOSE THE BEST.

	2)USE THE qlo COMMAND, THEN THE J & K KEYS. IF J<K, TAKE THE FOCUS OUT.
		IF J>K, TAKE THE FOCUS IN. ALSO, USE THE e KEY TO CHECK THE
		IMAGE QUALITY. MAKE SURE THE WINDOW IS COMPLETELY SQUARE. 
		OTHERWISE, YOU COULD BE ELONGATED WITHOUT KNOWING IT.

*** IF YOU SWITCH TO THE i FILTER, YOU SHOULD GO OUT (UP) 35.

*** REMEMBER THAT WHEN YOU ADJUST THE FOCUS IN, YOU MUST COME IN ABOUT 500 AND 
	THEN GO BACK OUT TO OFFSET THE EFFECTS OF GRAVITY.

*** IF, WHEN YOU TYPE e ON THE OBJECT, THERE IS A TAIL ON ONE SIDE, YOU NEED
	TO ADJUST THE FOCUS.

IV. OBSERVING
A. PARALLAX FRAMES
	
PI FRAMES MUST BE TAKEN WITHIN 30 MIN. TO AN HOUR ON EITHER SIDE OF THE 
	MERIDIAN ('ST' ON TCS).
	1) DO NOT SATURATE
	2) MAKE SURE FOCUS IS GOOD
	3) DELETE CRAPPY FRAMES
	4) MAKE SURE IN PROPER FILTER
	5) MAKE SURE POSITION PROPERLY SO YOU GET ALL REFERENCE STARS IN 
		FRAME. YOU NEED ABOUT 2K FOR THE REFERENCE STARS.

DO NOT DE-FOCUS PI FRAMES
HAVE TO INTERGRATE FOR 30+ SECONDS, USUALLY
MAKE SURE THE REF STARS ARE NOT SATURATED; IF YOU DO SATURATE THEM, TAKE 
	ANOTHER FRAME JUST FOR REFERENCE

ALWAYS TAKE A TEST FRAME IN THE SET-UP FILTER FOR THE SUGGESTED INTEGRATION TO
	ESTIMATE YOUR COUNTS. YOU SHOULD SHOOT FOR 50K, BUT WITH MOON 
	CONTAMINATION OR CLOUDS, 8-10K ARE OK.

GO TO THE TCS/MOVEMENT/SLEW POSITION

TYPE IN YOUR RA & DEC. MAKE SURE THAT THE EPOCH IS 2000.

WHEN THE TELESCOPE HAS STOPPED SLEWING,
TYPE test/object/40/test/dia/v  IN THE BLUE BOX (FOR EXAMPLE).
*** IT IS CRITICAL THAT YOU CHANGE FILTER WHEEL ONE TO dia FROM cb. ***

WHEN THIS TEST IS FINISHED, TYPE qlo TO CHECK IT.
	r FOR RADIAL PLOT TO CHECK THE SEEING & COUNTS
	a TO CHECK THE COUNTS
	e TO CHECK THE FOCUS

FROM THOSE COUNTS, YOU MUST CALCULATE YOUR INTEGRATION.

THEN YOU MUST OFFSET TO ENSURE THAT THE STAR IS POSITIONED PROPERLY. TO DO 
	THIS, TYPE offset/qq AND THEN THE X & Y PIXEL VALUES FOUND ON THE 
	SET-UP. THIS WILL GIVE YOU THE OFFSET VALUES.

	OFFSET HELP:
	E/W = RA; EAST = -, WEST = +
	N/S = DEC: NORTH = -; SOUTH = +

GO TO THE TCS. (MAKE SURE THAT YOU ARE NOT GUIDING!!)

UNDER MOVEMENT/OFFSET-ZENITH ENTER IN THE OFFSET VALUES. GENERALLY WHEN THE
	SLEWING CORRECTION HAS STOPPED, YOU CAN START GUIDING.

THEN TAKE ANOTHER TEST FRAME. TURN OFF GUIDING. AND THEN ANOTHER OFFSET. TURN 
	ON GUIDING.

WHEN THE SEEING IS BAD, USE F3 FOR (SLOW) GUIDING. (FAINT STAR)
WHEN IT IS GOOD, USE F9 FOR (QUICK) GUIDING. (BRIGHT STAR)

NOW YOU ARE READY TO OBSERVE.

TYPE observe/object/etc...
	MAKE SURE THAT THE NAME OF THE OBJECT IS ENTERED EXACTLY.

YOU MUST ALSO qlo EVERY FRAME TO GET COUNTS AND SEEING, WHICH ALL NEED TO BE
	ENTERED INTO THE LOG.

*** MAKE SURE TO RE-FILL THE DEWAR AT MIDNIGHT DURING THE LONG WINTER NIGHTS***
	RAISE THE PLATFORM. TAP THE HOSE A FEW TIMES ON SOMETHING METAL 
	TO DE-ELECTRIFY THE NOZZLE. IT IS FULL WHEN LIQUID STARTS DRIPPING 
	OUT ONTO THE PLATFORM.

IF THERE IS A FULL MOON, YOU NEED TO BE CAREFUL OF THE BACKGROUND COUNTS, AS
	THIS COULD SATURATE YOUR SCIENCE STARS. TO CHECK THIS, TYPE m AWAY
	FROM A STAR IN A BLANK PART OF THE IMAGE. THIS WILL TAKE THE AVERAGE
	OF 4 PIXELS AND GIVE YOU THE BACKGROUND COUNTS. YOUL SHOULD ADD THIS
	TO THE PEAK VALUE OF YOUR SCIENCE STAR TO ENSURE THAT YOU'RE NOT
	SATURATING.

B. PHOTOMETRY FRAMES

PHOTOMETRIC WEATHER:
	1) THIN CLOUDS OVER THE ANDES
	2) SLIVER OF CLOUDS OVER THE OCEAN
	
YOU DON'T WANT TO INTEGRATE LESS THAN 10 SECONDS; DEFOCUS IF YOU HAVE TO. 

IF YOU'RE GETTING PHOTOMETRY FOR A PI STAR, POSITION THE FRAME AS IF IT IS
	A PI FRAME (WITH ALL REF STARS); THEN YOU CAN USE FOR BOTH.

PHOTOMETRY STANDARDS:
	ALL SA FIELDS ARE GOOD.
	MAKE SURE YOU GET AT LEAST ONE RED STANDARD (GL644 IS BEST; GL0866 OK).
	GET TWO MULTI-STAR FRAMES AND 2 RED STDS.
	FINDERS IN PI BOX IN PHOTOMETRY NOTEBOOK
	SAVE STD. COORDS IN TCS (MARK/MOVE TABLE?)
	GOOGLE THE AIRMASS CALCULATOR
		GOALS: 1.1, 1.4, 1.9
	THEN PLUG IN SCIENCE STARS IN BETWEEN
	3-5K COUNTS OK FOR FAINT STARS
	
V. CLOSING DOWN
A. CLOSING THE DOME

IN THE CONTROL ROOM:
	TURN TRACK & DOME TRACK OFF.
	TURN DOWN FANS (ON SHELF ABOVE ARCON COMPUTER)

GO TO THE TELESCOPE
	ON YOUR WAY UP, TURN OFF LARGE FAN
	GO TO PLATFORM
	MAKE SURE MASTER POWER IS ON
	SLEW TO COVER POSITION
	CLOSE THE DOME
	TURN THE LIGHT ON
	PUT THE WINDSCREEN UP
	PUT COVER ON
	SLEW TO ZENITH POSITION
	FILL THE DEWAR
	PUSH IN 2 DARK SLIDES
	LOWER THE PLATFORM
	TURN LIGHTS OFF
	TURN MASTER POWER OFF
	
BACK TO CONTROL ROOM
	AT TCS BLACK BOX:
		DRIVES, AUTODOME, & MASTER POWER OFF

B. DATA MANAGEMENT
	1. CHECK THE HEADERS BY TYPING imhead IN THE RED. WINDOW. USE hedit TO
		CHANGE TITLES. MAKE SURE OBJECT NAMES ARE PERFECT!!!
		THEY SHOULD BE IN FORMAT: GJO866C @ V FOR PI (OR PHOT)
	2. MAKE .fits FILES:
		GO BACK TO ONE DIRECTORY AND CHANGE THE NAME SO THAT THE
			FORMAT IS 20060707-09.
		TYPE df TO MAKE SURE THAT THERE IS ENOUGH ROOM TO WRITE THE
			FRAMES. EACH .fits FRAME NEEDS ABOUT 2301120 BYTES.
		TYPE finishctiopi. THE FORMAT MUST BE 20060707.09.001
	3. ARCHIVE DATA:
		WRITE A COPY OF THE DATA TO A DAT TAPE USING THE CTIO36 
			WORKSTATION. TO DO THIS, MOVE TO THE DIR. WHERE THE
			DATA RESIDES (FOR EXAMPLE, cd /ua41/v12/20060070-09).
		THEN, GET INTO AN IRAF WINDOW
			mt -f /dev/nst0 status		TO CHECK STATUS
			tar -cvf /dev/nst0 *.fits	TO WRITE
			mt -f /dev/nst0 rewind		TO REWIND

		TO ADD DATA TO A TAPE THAT ALREADY HAS DATA ON IT:
			mt -f /dev/nst0 eof		eof = END OF FILE
			tar -cvf /dev/nst0 *.fits

C. FILL OUT A NIGHT REPORT. THIS IS FOUND AT 
	http://www.ctio.noao.edu/new/Tools/Forms/EON
	
	OR IT MIGHT BE FOUND UNDER THE BOOKMARKS ON THE CTIO36 MACHINE.

D. YOU SHOULD SHUT DOWN ARCON AND EXIT COMPLETELY OUT. OTHERWISE, YOU WILL
	PROBABLY HAVE TO RE-START ARCON THE NEXT DAY A FEW TIMES.




REBOOTING ARCON:
	EXIT ALL THE WAY OUT.
	LOGIN: V12
	PASSWORD: 34hSt46
	SELECT (2) IRAF WITH ARCON
	ANSWER yes
	set stdimage=imt2048
	THEN STRETCH WINDOW FOR FULL FRAME
	CLICK ON OPTION/MAGNIFIER
	THEN TAKE TEST FRAME
