Programme ID: 60.A-9284(B) version October 5, 2007. ...................................................................... * A non-editable section giving basic information on the run as scheduled: the ID, instrument, priority class, approved execution time, type (normal, large, guaranteed time, or director's discretionary time), and PI name This is a HAWK-I science verification run: Instrument: HAWK-I, various filters ID: 60.A-9284(B) PI: A. Fontana. priority class: ?? approved execution time: 80 hours type: ?? Science verification time ?? * aspects of the observing run: - General Description: a short summary of observing run, providing ESO with any information needed to meet your science objective. This is a straightforward imaging program with HAWK-I in the Y, J, K, NB1060 and NB2090 bands. The observing strategy is to integrate for several hours per filter on two pointings on the GOODS-S region. The lower (GOODS-1) has a YKJ/NB2090 coverage; the upper has a NB1060/Y coverage. The exact coordinates of the pointings are supplied below. For acquisition we recommend the HAWKI img_acq_Preset acquisition template. Finding charts of the entire field is provided. The science integrations should be executed with the img_obs_autoJitter template, for a total of 60 minutes integration, and a JITTER WIDTH of 30 arseconds. A different random seed should be given in SEQ POISSON for each OB. OB DETAILS. each OB is designed to be of 1hr exposure time (see waiver section). DIT, NDIT and NEXPO are detailed below. They are based on the existing hawk-I Manual, feel free to modify them following the commissioning results. The list below IS A PRIORITY LIST.

To improve the efficiency significantly we request a waiver for the 1 hour OB limit. Our targeted science integration are 60 minutes per pointing, about 70-80 minutes including overheads. Splitting the science integration up into OBs shorter than 1 hour would lead to inefficient observing. We understand and accept that OBs slightly longer than 1 hour may not satisfy the seeing limit fully. If the seeing gets worse during the OB, please do not stop it ! Just keep going and finish the OB. We have found that OBs finished in this way are almost always fine. -- Critical Observing Conditions Constraints: any information about required observing conditions that are critical for the achievement of the goals of the project. To reach the science goals of the program we request a seeing constraints of < 0.6" in the Y band. Other bands may be observed up to 0.8" of seeing As stated above, please do not be strict in the acceptance of these seeing requirement. Since the final Y images will be the superposition of 15hr of exposure, we can tolerate a marginal worsening of the seeing. We expect the Y band to be somewhat sensitive to the moon phases, so we would prefer relatively dark conditions, although we understand that the SV dates are fixed. We request a minimum distance to the moon of > 30 degrees. We request that no observations are taken within 20 minutes of zenith (this would cause a bad skysubtraction). We request an airmass lower than 2.0. Observations in the K band can start when the sun is down. There is no need to wait for astronomical twilight, civil twilight is fine - there is no enhanced background in K. -- Time-Critical Aspects: if your OBs must be executed within specific time windows or in some time specific sequence, please describe those constraints here. Note that in the case of specific time windows, these need to be indicated also under the Time Intervals information in the OB itself. There are no time critical aspects. -- Special Execution Requirements: any other requirements regarding the execution of your run other than those indicated in the previous sections, such as preferences on the relative completion of OBs; for instance, if preference should be given to the completion of all the OBs on a given target before proceeding with another target. The list above is sorted by priority, and we request that each filter is completed before starting the next one - apart from the seeing issue. -- Special Calibration Information: if you have submitted OBs for calibration, please describe them here, why you have submitted them, and how they should be executed relative to your science OBs (e.g. same night, once per observing run, etc.). In particular, you must provide the magnitude and spectral type for all user supplied photometric or spectrophotometric calibration stars. We require no special calibration observations. A good flatfield is the most important thing we need. -- ToO Information: please indicate here if this is a Target of Opportunity run and give any special details. This is not a ToO run. -- ToO Activators List: please give here the names of the investigators who are authorized to trigger a Target of Opportunity observation. Not applicable. -- Pre-Imaging Requirements: if this is a pre-imaging run, please indicate it here and describe any special requirements; for instance the need to obtain on- and off- observations in narrow-band filters contiguously. This is not a pre-imaging run, * An entry for the e-mail address of the Principal Investigator of the programme. fontana@oa-roma.inaf.it * Estimated Total Execution Time: please include here the execution time as given by the execution time report of P2PP. Assuming overheads as in sec 4.5 of the P81 HAWK-I manual, and AutoJitter template settings described above, we expect: Y band 16 hr exposure, overhead 14% = 18.2h NB2090 3hr exposure, overhead 10% = 3.3h K band 16 hr exposure, overhead 28% = 20,5h J band 8 hr exposure, overhead 25% = 10h for a grand total of 52 hours. * Is this a Pre-imaging run? this is a tick box that must be checked if the run is pre-imaging for another run. This is important to ensure that pre-imaging runs receive the due execution priority. no. * In case that the pre-imaging run is checked, you must indicate the Source of Pre-imaging in the corresponding box. If the source is none of those listed there, you can indicate the actual source in the entry below it. Not applicable.
