README Template 70.1 ESO Programme ID: 70.D-0652(D) Principal Investigator: GianLuca Israel Contact Person Name: GianLuca Israel Contact Person E-mail Address: gianluca@mporzio.astro.it Contact Person Telephone Number: +39-06-94286437 Instrument: ISAAC OPC Priority Class: A OPC Approved Total Execution Time: 6h Estimated Total Execution Time (including overheads): 6h README File Submission Date: 19 August 2002 Program Description =================== General Overview ---------------- This is an imaging program consisting of fast photometry of a realtively faint and pulsating (period of 5.4min) object. Since we need at least 10 measurements per cycle we set DIT*NDIT = 30s repeated 2 times for each telescope offset in order to keep (DIT+4.1)*NDIT*EXPOSURE > 60s as requested by ISAAC. There are 6 OBs for photometric standards, which should be carried out at the beginning and at the end of the scientific OBs. It could be that exposure times should be (manually) modified depending on the seeing conditions at the moment of OB execution. The standard, FS16, has been choosen from the UKIRT fundamental list. Magnitudes are: J=13.0 , H=12.7 and K=12.6 . Note that FS16 is also one of the standards for which a pre-defined ISAAC template is available at VLT. We checked, by using the 2MASS cataloge, that there is no bright object within 3' from the target position. The brightest object is a J=12.7 star at 2.9'. Waiver Request Summary ---------------------- We requested to perform the about 3.5h execution time OBs related to the J-band monitoring within one night and without intterruption. This in order to study in greater details the profile and phase of the 5.4min modulation. Waiver ID: 70.D-0652D.01 Critical Observing Condition Constraints ---------------------------------------- None Time Critical Aspects --------------------- If possible we prefer to have an uninterrupted run. In case of splitting into different nights we request to execute, within the same night, the target J-band OB in order to rely upon a broader time interval for the study of the 5.4min modulation. In any case we need two photometric standard measurements for each night. In case of exposure gaps due to technical or whether problems we ask to extend the observations beyond the 6h to compensate for the time lost. If the observation is stopped for any reasons before 3hr observation the proposal aim will be not reached. In this case we will ask to repeat the observation. 8.5h XMM observation has been accepted in order to check, among other things, the optical/X-ray peak phase-shift stability with respect to the VLT/Chandra simultaneous observations carried out on November 2001. In the case the XMM pointing will be scheduled during the ESO period 70 we would like to request a (nearly)-simultaneous (within 1-2 nights depending on the accuracy of the ephemeris at the moment of the X-ray observations) VLT observation. Note that the XMM Cycle 4 will start on September 2002. If this will happens the PI of the proposal will contact the Paranal staff in order to check wheather it is possible to arrange the ISAAC observations in order to overlap the XMM observation. Below are the e-mail addresses and phone numbers of the people which can take decisions concerning this observations. The second person can be contacted in the case of not availability of the PI.

Gianni Marconi - gmarconi@eso.org uff +56-24633118 Special Calibration Information ------------------------------- As already mentioned photometric standards OBs should be carried out at the beginning and at the end of the scientific OBs. It could be that exposure times should be (manually) modified depending on the seeing conditions at the moment of OB execution. The standard, FS16, has been choosen from the UKIRT fundamental list. Magnitudes are: J=13.0 , H=12.7 and K=12.6 . Note that FS16 is also one of the standards for which a pre-defined ISAAC template is available at VLT. ToO Information --------------- Not applicable Pre-Imaging Information ----------------------- No pre-imaging is required for this programme. Note that the finding chart attached to the OBs is based on a SOFI observation (J-band) of the target.
