FORS2 LSS spectroscopy of one new gravitational lens system. The P.I. wants two different orientations of the slit, indicated in the finding charts. Since it is important to seperate each component of the gravitational lens spatially, the user has requested and been granted a waiver to use the HR collimator and 1x1 binning rather than the default FORS2 LSS settings. For this reason, also calibration OBs (Dark, Bias, Arc, Flatfield) have been submitted by the user. However, a standard photometric standard taken with 2x2 binning is Ok to the user. The P.I. also wants the OBs for this run to be carried out as closely possible in time to the OBs for the associated ISAAC run 71.A-0407(E). Since these have already been carried out (on April 12/13), this run needs to be completed as soon as possible!
