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

• flush x20

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

• ARC J 0150-0153

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

• airmass 1.5

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

• ARC 0183-183

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

• 0200-0202 taken by mistake while telscope waas moving
• J 0203-0212 2300-3500counts 0223-0232 9800-1700counts 0243 saturated
• H 0213-0222 2000-3500counts 0233-242 9000-18000counts 0244-0253 26000-30000counts
• Ks 0254-0303 6500-23000counts

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
