Guiding Options

Two guiding options are available, the F2 On-Instrument Wavefront Sensor (OIWFS) and the telescope's Peripheral Wavefront Sensors (PWFSs). The F2 OIWFS is currently in its last stages of commissioning. It is expected to be available during 2015A, but targets with RA<10h may be observed with the PWFS2. Once the OIWFS is fully available, it will be strongly recommended that the F2 OIWFS be used for all but non-sidereal objects. This is because (1) the PWFSs vignette a large part of the GMOS science field and (2) there is significant flexure between F2 and the PWFSs.
