S/D/E Observing - LUCI2 - UT20151124

### LUCI2 "Service" Observing - UT 20151124
luci2.20151124.NNNN.fits

Summary:

• INAF: Antonniucci_7 v2492_cyg Completed, significant edits needed
• LBTB:Wuyts UDSK VClose to moon, skipped
• LBTO:Rothberg NGC_34 Completed, use shorter acq times for bright targets
• INAF/Iovino 2015_2016_5_zJ_spec Problem w/LMS file, skipped
• LBTO/DThompson hero005 Completed
• LBTO:Rothberg UGC_2238 Completed, use shorter acq times for bright targets
• INAF/Antonucci v1647_ori Completed, significant edits needed
• LBTB:Wuyts M2333cosk2 Did 1.83 hrs (22 x 300s)

Problems:

• Had to restart the scheduler twice. It might be related to inserting/skipping pauses. Note sent to Alexander
• Mask with only 1 offset star (RTD requires boxes around all alignment stars for now), won't work
• Several scripts heavily saturated the targets...use the ETC!
• LUCI2 G210 grating having trouble stabilizing for K-band CWL < 2.24um. Note added to "writing scripts" page

0001 0002 1x2.74s dark to check readnoise (LS0.5" in FPU)

12:34 Init all units in LUCI2 ... OK

Mirror is 2.6 degrees warmer than outside
Clear at sunset

### INAF: Antonniucci_7
README says 0.75" slit, scripts made up with 1.00 arcsec. Bright sources, so I
switched to LS_0.50arcsec as they can always degrade the resolution.

12:50 v2492_cyg_tell_LS0.5.xml

• Initial seeing on the guider is 0.6"
• zJspec is bright, HKspec likely saturated in 5.0s

01:03 v2492_cyg_tell_LS0.5_3s.xml

• Modified to do DIT=2.75s
• Image quality on the acq image is terrible!
• Last file: 0016

01:12 v2492_cyg_LS0.5.xml

• Acq: +0.15" dX done manually to center on slit
• Acq: +0.15" dX done manually again
• 0.45" on guider images
• zJspec data look good
• HKspec data look close to saturation

Remade HKspec script: v2492_cyg_LS0.5_180s_HKspec.xml

• Changed to 6x[1x180s] exposures, first offset to recenter
• Still too close to saturation! Aborted

Remade HKspec script: v2492_cyg_LS0.5_60s_HKspec.xml

• Changed to 6x[1x60s] exposures, first offset to recenter
• Still too close to saturation! Aborted

Remade HKspec script: v2492_cyg_LS0.5_20s_HKspec.xml

• Changed to 6x[3x20s] LIR/INT exposures, first offset to recenter
• OK now, ~22000 ADU peak in the spectrum in 20s

02:33 v2492_cyg_img.xml

• DIQ is not great
• Completely saturated!

02:44 v2492_cyg_FeII_img.xml

• DIQ is not great
• 26k ADU in 2.75s

--> mv v2492_cyg* DONE

### LBTB: UDSK

02:50 M2337udsk_tell.xml

• No README with scripts
• No FC with slits identified for telluric star (was understandable from offsets)
• Very close to the MOON !! Skipping this one tonight
• Guider did not find the guide star, background very high

### Rothberg: NGC_34

02:54 HD_219833_Telluric_2pt27.xml

• Script out of sync with instrument configuration (udsk mask still in the FPU)
• Scheduler restarted
• Reset GEIRS on READ2 gui (take test exposure...OK)
• Refresh on LUCI2 gui...OK

03:02 HD_219833_Telluric_2pt27.xml re-loaded and re-sent

• Mask moving now
• EL~44 setting
• 20x3.0s in K for acquisition of a telluric ???

03:17 NGC_34_V2_2pt27.xml

• 20x3.0s for acquisition was overkill, sky also probably not needed
• ~16k ADU peak in the blue end of the spectrum

### INAF/Iovino

04:26 2015_2016_5_zJ_spec_tell.xml

• EL~50, rising. Guider around 1" now
• Incorrect mask ID in script. Was ID993628, should be 993628.XXLrev

04:32 Running Corrected_zJ_spec_tell.xml

• LMS file not in the working directory - downloaded from luci.luci
• MOS acquisition is not working, sky image seems to be missing

04:50 Corrected_zJ_spec_tell.xml (again)

• Cannot acquire mask. not sure where the problem is. Skipping
• Looks like RTD only sees a single reference star for alignment

### LBTO/DThompson

05:04 hero005.xml

• Very near moon, but the guide star was found
• Seeing 0.8"
• Can faintly see the target continuum in the K band

### LBTO:Rothberg

~07:00 observed telluric HD18571_Tell_2pt27

07:15 acquiring UGC_2238_2pt27

• Seeing 0.7" on guider
• Thin cirrus coming in from West

07:25 started spectroscopic observation

### INAF/Antonucci_7

08:30 v1647_ori_60s.xml

• Source is 10th mag in K, 14th in J
• Changed the spectroscopic exposures to 60s
• 0.62" seeing
• 7k ADU max in zJspec, saturated in HKspec

### INAF/Antonniucci_7

09:02 v1647_ori_10s_HKspec.xml

• Original script saturates in HKspec
• Changed to 6x10s LIR/INT HKspec only to redo it
• 24k ADU per DIT

09:12 v1647_ori_tell_2.75s.xml

• 29k ADU max in HKspec spectrum

09:24 v1647_ori_img_2.75s.xml

• Guide probe is visible on detector, left of science target
• Seeing got worse, now ~1.5"

### LBTB/Wuyts

09:33 M2333cosk2.xml

• Could not do the telluric before...EL=17!
• MOS acq, then +0.15" manual dX offset (no image taken)
• G210 @ 2.20um stabilized OK
• Seeing a bit variable, 1.0-1.3", 1.1" avg.
• Emission-line source seen in bottom slit in all exposures I checked

12:01 M2333cosk2_tell.xml

• Aborted...scheduler needs restart after a pause that gets reset?
• Dithers between 3 slitlets worked well

12:13 Closing dome

### Calibrations

12:27 M2333cosk2_cal.xml

• Starts at file 0179
• Grating not stabilizing at 2.20um. It did not have any trouble on sky.
• Tried manually setting various wavelengths, no luck @ 2.2um

12:49 Cal_0pt5_210K_V3_2pt27.xml

• Failed to lock @ 2.27um
• Accidentally moved COSK2 mask in when trying manually toi tilt grating

01:01 M2333cosk2_cal.xml

• Failed to lock @ 2.2um
• Continued script (log says grating unlocked)
• Flatfields might still be OK
• Still failing..."continue" on script continues unlocked

01:19 Cal_0pt5_210K_V3_2pt27.xml

• Trying again...worked?

01:50 Doing some calibrations by hand

G200 LS_0.50arcsec 1.175 zJspec

• 0232 0236 1x3.0s Halo2 lamp off

• 0252 0256 1x30.0s Halo3 lamp off ~3.5k ADU

G200 LS_1.00arcsec 1.175

• 0262 0266 1x30.0s Halo3 lamp off ~0k ADU
• 0267 0271 1x30.0s Halo3 lamp on ~1.5kk ADU
• 0272 0276 1x3.0s Halo2 lamp off ~0k ADU
• 0277 0281 1x3.0s Halo2 lamp on ~4.5kk ADU

Still need to run calibrations for
Arcs, if you don't want to use OH lines



>>> Need to adjust the LUCI2 field stop before tomorrow
