In order to have the optic at the correct height the position of the F0 keystone must be set according to the current value of the F1 keystone postion using the formula in the table below. The reason for this is that the F1 fishing rod does not work and the height cannot be set without using the coil-magnet actuator, which for this case a large nuber of counts would be needed. ||<tablewidth="1007px" tableheight="151px">'''Filter''' ||'''LVDT readout (µm)''' ||'''klog''' ||'''Notes''' || ||F0 ||-1263 µm - (F1 position) ||[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=7900|7900]], [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=8135|8135]] ||'''Depends on the F1 position because the F1 fishing rod is not operational.''' || ||F1 ||F1 position ||[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=7900|7900]], [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=8135|8135]] ||The fishing rod does not work. || ||BF ||0 || ||We require the IM-V OSEM flags to be at the correct position. || |
