- Fill the dewar every afternoon

 

Setting up the Hamilton

Camera room (four things)

1) open echelle grating

2) open collimator – put in mask

3) open cross-disperser (slide out front and lift side panels)

4) fill the dewar

Is the CCD controller temp correct? (-120 for dewar 8,  -116 for dewar 6)

 

Slit room

1) I2 cell now on motor – controls on panel above Hamilton spectrograph controller

2) Check I2-cell orientation on first night with laser

3) Power on I2 cell temp controller and press ÒstartÓ

4) Fan on medium, drawing air

 

    

 

      

Set up computers

1) Data Taker: pull down Shane menu: ÒData Taker ShaneÓ

2) Hamilton spectrograph controller: pull down Shane menu: ÒhamitÓ

3) Photon integrator: in xterm, type ÒshowmidptÒ (pull down menu not currently working)

4) I2 cell motor: pull-down Shane menu: Òslitroom_feÓ (slitroom front end)

5) Event sounds: pull-down Shane menu: ÒeventsoundsÓ 

6) Coords program: pull-down Shane Misc menu: ÒcoordsÓ

 

Logsheets:

Log on to plato, copy last logsheet to current one and edit.

 

 

 

 

 

Focus

1) Hamilton spectrograph controller (ÒhamitÓ)

            Aperture plate (decker ÒdÓ, focus: ÒaÓ 100 micron, 2.Ó5 slit)

            Lamp: ThAr (5)

            Filter: clear (1)

2) Data-taking window:

            Exposure time (B) = 20 sec

Display size: nr=1700  nc=1851, sr=0  sc=100

Shutter: open

            Binning = row: 1, column: 1

            Obs Type = Fast

            DonÕt Record (written to scratch directory for foc.pro)

            Object Name = focus

            Is the ThAr  ÒAÓ line in the proper position at 760, 800?

3) Run foc.pro on gouda (computer)

            idl> foc, /plt, /mark, /hi_rho, /shane

            Once the best focus has been found, turn Recording on

            and save the best focus image to /data/hamshane directory

4) Update the logsheet with current CCD Focus, Grating, Height settings.

 

Flats

1) Data-taker (take 30 if possible)

            Exposure time = 1.5 sec

            Window size:  nr=1700  nc=1851, sr=0  sc=97

            Shutter: open

            Binning: 1x1

            Obs Type: fast

            Record

            Object Name (I) = wideflat

2) Hamilton spectrograph controller

            Aperture plate (decker ÒOÓ 640 micron, 5Ó slit)

            Lamp: Polar Quartz (8)

            Filter: bg13 (3)

3) on gouda xterm window: igetham 30  (takes a set of 30 exposures)

4) Check the first image for problems – e.g., no I2 lines, right count level, recorded

5) Repeat with integration time of 5.5s, polar qtz and bg12 filter: igetham 30 

 

Iodine

1) in the slitroom_fe window, pull down ÒfunctionÓ window and insert I2 cell

   (did you turn on the temp controller?  Does the temp controller read 50C?)

2) Hamilton spectrograph controller

            Aperture plate (decker ÒLÓ 640 micron 2Ó slit)

            Lamp: Quartz (8)

            Filter: bg13 (3) to start

3) Data-taker

            Exposure time = 1.5s, but depends on quartz intensity

            Window size: nr=1700  nc=1851,  sr=0  sc=100

            Binning: 1x1

            Obs Type: fast

            Record

            Object Name = iodine

4) Start the exposure, but ÒSelect to PauseÓ in the data-taker window after 1.5 sec. Change to a bg12 filter and resume to complete the exposure.

5) Check the spectrum – I2 lines present?

 

ThAr

1) Hamilton spectrograph controller

            Aperture plate (decker ÒLÓ 640 micron 2Ó slit)

            Lamp: ThAr (5)

            Filter: clear (1)

             A line should be around 760, 1280 (not 800!)

3) Data-taker

            Exposure time = 3s

            Window size: nr=1700  nc=1851,  sr=0   sc=97

            Binning: 1x1

            Obs Type: fast

            Record

            Object Name = ThAr

 

Observing

1) Turn on photon integrator: flip 2 switches, dial to 710 V, pull plunger

2) On gouda: be sure you have ÒcoordsÓ window up and read in observing script

            (note: ÒyesÓ enable POCO on gouda)

3) Be sure ÒshowmidptÓ program is up and running

 

          CAT

a) Open up the CAT telescope (housing, then siderostat, upper shutter then mirror cover,  pull and twist ceiling cover, put in 5th mirror, turn on tracking)

b) Start guider (click ÒCATÓ on bottom menu bar, Òreset to default values in parameter window, check that guiding apertures are over slit and that TV camera is focused)

c) Set on Bstar, 10 minutes before 12 degree twilight

d) Check telescope focus

e) Start autoguider (ÒStart CAT Guiding,Ó enable auto-guider by flipping toggle on instrument panel)

 

         3m

a) direct the telescope operator to the starlist

b) select target star and ÒSend to POCOÓ

4) Update exposure times and object names in data-taker

5) Update logsheets (spaces, no tabs in logsheet)

End of the night

1) If no Bstar observed at the beginning of the night, observe one now

         CAT

a) toggle off autoguider

b) turn off software guider tracking

c) stow telescope

d) close housing (mirror cover, upper shutter, siderostat cover, housing, swing out 5th mirror, twist ceiling cover to close)

2) Turn off photon integrator (push in plunger, dial down voltage, flip two switches)

3) Take one I2 observation

4) Take one ThAr observation

5) Take a second set of wide flats

6) Check (and fix) logsheets

            on plato: idl> logchecker

Advanced observers:

a) ftp logsheets to Berkeley or SF State

b) run barylog

c) set up raw reduction script at SFSU

d) start ftpÕing raw data to SFSU

7) go to sleep!

Advanced observers:

e) run raw reduction script after waking up

 

End of the run

1) In the slit room: make sure the I2 heater is off, cover cell, turn off fan

2) Close up the optics in the camera room

3) Have all data been ftpÕd to SFSU?  All logsheets?

Advanced observers:

            Has barylog been run on all logsheets?

            Is the latest and greatest bcvel.ascii file at SFSU?

            Have all raw reductions been run?

            Has barystruct been run on the SFSU bcvel.ascii file?
