Observing Plan (copy and paste this to the nightly logs)

LUCI1 Daily functional checkout:

• Run /home/engineer/bin/showSupervisorStatus.sh, check if OK
• Check LUCI1 Web-IO Control, verify that ROE and MCE are powered
• Check is calibration unit is in the out position
• Open UI and check that telescope data are being updated
  • If not, restart Telescope Service through SW Control Center
• Verify data are moving to archive

LUCI1 Weekly Operations: (do prior to each partner science block)

• Check darks (see: LBTtools/LUCI/readnoise script)
  • O2DCR 2.0s (usually around 11.6 e-, 12.6 for detector #2)
  • MER10 10.0s (usually around 5.5 e-, 7.75 for detector #2)
• Check/adjust Pupil and Field Stop Alignment
  • Detailed instructions here (for now): https://dl.dropboxusercontent.com/u/51728588/Pupil_Field_Align.txt
• Check /data/luci, make room if necessary
  • login as luci@lucifer (must be the owner to delete files)
  • Before deleting data from lucifer, check /Repository/
  • If discrepancies are found:
    • Check /newdata/indir, /newdata/warning
    • Check the archive web interface
  • If necessary: cp /archive

LUCI1 Monthly Operations:

• Check system time vs our GPS, at cmd line execute: "ntpdate -q gps0.mountain.lbto.org"
• Check mask tables after exchange on the Mask Config GUI
  • Make sure the column 'in use' does not have a check mark where there is no mask.
  • Make sure there are no blank spaces before the mask name
  • LMS files:
    • Make sure the path name is correct
    • Verify the lms files exist in this directory on the lucifer computer.
• Shutdown and restart LUCIFER Control SW after mask exchange
• Take sieve mask images in N3.75 and N1.8 to check focus gradients
• Move calibration unit in
  • Check that lamps work
  • Check gratings/tilts
  • Take an imaging flat and check levels, dirt on window
  • Move calibration unit out

Other Tests:

Closed dome SW tests, if requested

• Test sound playing through IIF (write iraf task to do this)

Twilight flats in NB, BB filters (cycle through all over time)

• Need to set up a records page on the wiki to keep track

Correct initial collimation/pointing

Open dome SW tests, if requested

• Optical pointing/co-pointing/range balancing algorithm, also using IRTC

Take set of linearization test data (photometric weather only!)

• Preset to any Persson standard using the catalog interface
• source the shell script ~/LBTO/SciencePrep/LinTestData/lintest
• There is a README file in this directory describing the test
• Should take ~25 minutes to run.

Test any new template observing scripts prior to release

Run science-type dice5 pattern to check that things still work

• Preset to available BS91XX star from UI/Catalog
• Execute script: ~/LBTO/SciencePrep/dice5_10x (~1 hr)
• Any other source with a known ABS dither pattern is OK
• Calculate rms/position, scale & rotation of pattern

Repeat check of dithering along slit (20x 2' dither)

• Preset to available BS91XX star from UI/Catalog
• Execute script: ~/LBTO/SciencePrep/slitdither.acq
• Align BS source to center of 2" longslit
• Execute script: ~/LBTO/SciencePrep/slitdither.sci (~30 min)
• Calculate AGw alignment to slit

Collect open-loop tracking data to check stability

• Preset ACTIVE on BS91XX to collimate
• Preset track to same source
• Collect long series of 30x10s exposures, saved NORMAL

Repeat measurement of focal plane scale, orientation

• Any low-latitude field with 20+ stars in USNO is OK
• Random fields OK, or some BS91xx fields with lots of stars
• Execute script: ~/LBTO/SciencePrep/imagepair

Additional work on M1/M2 range-balancing collimation

Field aberration data collection

Check existing collimation model

• Collimate at mid-EL
• Check at low EL w/TRACK preset
• Check at high EL w/TRACK preset

Check existing pointing model

• Implement new collimation model first, if necessary
• Correct pointing at mid-EL
• Check a few points
• Stable conditions!
• It would be useful to take a set of 12 points if possible
• Use the "pointing" mask for focal plane measurements.

Photometric zero point and extinction monitoring

Collect a "movie" of 2s LUCIFER images while an in-field offset is taking place.

• Check to make sure offsets still happen in a reasonable manner

Improve map of AGw patrol field limits at high field angle

• Requires set up work on a stone field

Gather NB illumination correction data (BrG done on 20100606)

• Needs photometric weather
• See ~/LBTO/SciencePrep/Illumination/README.txt for info

Field Check - verification of WFS algorithm

• Needs decent seeing, stable conditions
• http://wiki.lbto.arizona.edu/twiki/bin/view/Commissioning/ComTools#Field_Equations_Check_Measuremen
• Script will take ~2 hours to execute

Continue gaining experience with LUCIFER on-sky (e.g. spec acq.)

Test dithering between extreme slits on MOS mask + telluric

• Manual needs 0.59836mm/" scale for the dXdY calculation
• The how-to set up telluric observations needs updating for clarity.

Investigate variable imaging FF gradients

• Take data while the telescope is offset with respect to the enclosure
• Take data at PA=X, PA=X+180

Tests that have been satisfactorily completed and do not need repetition:

Re-test updatePointingReference functionality (high priority) (June 2011)

• See description wiki page here
• Scripts are in ~/LBTO/SciencePrep/zeroBase
• Manually preset to BS91XX star at non-cardinal PA
• Execute appropriate offset script(s)
• Ask OSA to "absorb" in the appropriate coord sys.
• Execute appropriate dice5 script(s)
• 9 blocks x ~5 minutes each

Test WCS/ROTCEN Coordinates issue

• Preset to any Persson standard, allow to collimate
• cd ~/LBTO/SciencePrep/WCStest (there is a README file)
• ./wcstest.sh (executes setup then the four dice5 scripts)
• Should take less than 30 minutes.
• Result: CRVAL1/2 in header walks off where it should be...next step in PCS

Test defocus on AGw by 13mm, Johanna's acq script

• Need decent (<1") seeing.
• Ask OSA to do the following on obs1:
  • Edit /lbt/tcs/current/etc/GCS/AIP_L.cfg
  • change "focus" to be 44 instead of 31, save
  • selectAGW left AIP_L.cfg
• Preset to target field:
  • ~/LBTO/2011.02/WASP12b_acquisition_longslit (06:30:32.7907 +29:40:20.440)
  • Use any Persson standard if WASP12b is not up
• Allow AGw to re-collimate (wait for collimation ON)
• Can execute the corresponding science script if on WASP12b (at least 1 pair of spectra)
• Ask OSA to do the following on obs1:
  • Edit /lbt/tcs/current/etc/GCS/AIP_L.cfg
  • change "focus" back to 31, save
  • selectAGW left AIP_L.cfg

DThompson notes (not part of plan above)

• Investigate illumination changes in twilight flats, build library of flats
• Improve collimation
• Improve pointing
• Work on co-pointing SX and DX
• Measure/correct field aberration issues (aligns optical axes of M1, M2)
• Monitor orientation of detector on sky
• Diagnose a possible WCS issue (reported last week by INAF)
• Monitor/correct AGw transformation
• Investigate photometric gradients (BB=5%, NB=25%)
• Test new functionality (TCS and/or LUCI)
• Test various approaches to scripting
• Monitor photometric zero points

# * Take a set of (monocular) range-balanced collimation data # * Stable conditions! # * implement this collimation model

# * Take a set of pointing data using range-balanced collimation model # * Stable conditions!

# * Collect field aberration data

# * Collect through-focus sequence for Andrew - reasonably dense star field. # * Try Z4 of -1000, -500. 0, 500, 1000 nm # * Also check the AGw-LUCIFER focus in cold weather for temp term?

# * Collect astrometric field data to check AGw calibration for monitoring
