The observing campain is a pilot study, intended to further develop the method of Surface Brightness Fluctuations for distance determinations of galaxies towards spectroscopic investigations of marginally resolved or unresolved stellar populations in nearby galaxies. Observations will be conducted with the integral field spectrophotometer PMAS, which has a mode for 3D spectroscopy, as well as a direct imager, and which is a unique instrument world-wide.The travel grant is requested for observers Prof. Dr. Martin Roth and Hardy Drube, who shall conduct the Calar Alto observing run, which has been granted for 5 nights, dating September 21 - 25, 2012. In addition to the observing nights proper, two more days for preparation and completion after the run are necessary.PMAS observations require the presence of two observers in order to guarantee the appropriate and efficient operation of the instrument, as well as performing online data reduction and visualization, without which the success of the programme and adequate use of telescope time would be in question.

观测活动是一项试点研究，旨在进一步发展用于确定星系距离的表面亮度波动方法，以进行附近星系中边缘分辨或未分辨恒星种群的光谱研究。观测将使用积分场分光光度计PMAS进行，该分光光度计具有3D光谱模式，以及直接成像仪，并且是世界上唯一的仪器。申请旅行补助金的是观测员Martin Roth教授和哈代Drube博士，他们将进行卡拉尔阿尔托观测运行，该运行已被授予5个晚上，日期为2012年9月21日至25日。除了正常的观测夜晚之外，还需要两天的时间进行准备和运行后的完成，PMAS观测需要两名观测员在场，以保证仪器的适当和有效运行，并进行在线数据简化和可视化，否则方案的成功和望远镜时间的充分利用都是有问题的。
