FORS2 MXU spectroscopy of gravitational arcs in one massive galaxy cluster. One target, two MXU masks. 10 OBs, evenly distributed over the two masks. Apart from reasonable seeing (0.8"), and reasonably dark time, no stringent constraints on observing conditions. A waiver has been granted to allow the user to use OBs with a duration longer than 1 hour, under the usual conditions that OBs will not be repeated if conditions degrade over the course of the observation.
