Details
Begin night with Lucifer
01:52 - Start with flats for yesterday's imaging of Turatto
- Ks
0002-0011
(17000-4000counts), 0012-0021
(>4000)
- H
0022-0031
(7000-5000counts), 0042-0044
- J
0032-0041
<6000counts
- the counts are low, if we have time we will have to repeat at the end of the night
02:02 - Pointing correction and collimation
02:15 - Slew to Gallerani SDSSJ1048+4637_ref for acq
0045-0049
- centering on the target and not the reference star
- after l'acquisition we have flushed the detector because the previous nights we had seen persistence - 2x10
02:38 - SG9_spec_science_Z_5.txt
0050-0061
- seeing measured on the images 0.8''
- seeing on the dimm is variable ~0.7''
- we can still see some persistence on the firts spectra - maybe we should flush more...
03:44 - SG9_spec_science_Z_6.txt
0062-0073
- Y-9.5 to recenter the object
- we flush the detector again
- seeing measured on the image 0.9''
- during the 11th offset the guide star could not be reached and it was not guiding for 2 min.
04:56 - Tell acq for Gallerani
0074-0078
05:06 - Telluric science script for Gallerani in Z band
0079-0081
05:08 - Error commiting instrument setup - error grating unit
- we repeat script but error persists
- we change from grating to mirror - resend preset - problem solved
05:10 - Telluric science script for Gallerani in J band
0082-0084
- Y-4 to center it again
- airmass 1.0
05:17 - Slew back to target - Calib Unit IN
- ARC J
0085-0088
- ARC Z
0089-0092
- FLAT Z
0093-0104
- FLAT J - error with grating - abort script
- we decide to do calibration in daytime - Calib Unit Out
05:40 - Gallerani SDSSJ1048+4637_ref for acq
0105 -0108
- we tried to do acquisition without taking off the slit and applying the old offsets X+1.7
- we center source
05:57 - SG9_spec_science_J_1.txt
- abort because we realise we centered the wrong source
06:04 - Gallerani SDSSJ1048+4637_ref for acq
0109-0113
06:17 - SG9_spec_science_J_1.txt
0114-0125
- seeing measured on the image 0.9'' -1.1''
- seeing on the dimm 1.2''-1.3''
- we did not flush detector - persistence in the first image
07:24 - SG9_spec_science_J_2.txt
0126-0136
- offset Y-9.5
- seeing measured on the image 0.7''
- seeing on the dimm 0.8''
08:31 - SG9_spec_science_J_3.txt
0137-0149
- offset Y-9.5
- seeing measured on the image 0.7''
09:37 - Calib Unit IN
09:46 - Calib Unit Out - Slew to Tell acq for Gallerani
- preset cancelled - no star found
- moving calib unit in/out - no result
- correct pointing
09:53 - Repeat Tell acq for Gallerani
0154-0160
10:04 - Telluric science script for Gallerani in J band
0161-0163
10:08 - MOS acquisition for Maiolino HDF_K2
0164-0167
10:39 - Science script HDF_K2_2
0168-0179
- average seeing on the AGw - 0.7''
11:45 - Calib Unit IN
11:49 - Calib Unit OUT - Slew for Tell acq
0184-0192
- The first offset is to put the source in the slit it is not correct
- we had to calculate offsets by hand...
12:12 - Spec science for Tell Maiolino HDF_K2
0193-0199
- at the 6th offset the guide probe could not reach the position and the preset was cancelled
- we commented that offeset and we did the last two - where a spectrum appeared in the slits
12:24 - Slew for flats
-

13:05 - Calib Unit in
- Flat J Gallerani
0304-0315
- better not to be used because of possible persistence after saturated K flats.
- Flats for this configuration can be found in 20110403
13:35 - End of Night -
DoDarks
- Darks at the end of the night are also affected by percistence - the 300sec have double counts than usual
- Better use the ones obtained at the beggining of 20110403
