Guiding Options

Two guiding options are available, the F2 On-Instrument Wavefront Sensor (OIWFS) and the telescope's Peripheral Wavefront Sensors (PWFSs). F2 OIWFS is available for science observations requiring image quality within the IQ 85%-ile. Please consult with your program contact scientist about the convenience of using either guider*.   

More work is planned during 2017A for achieving an image quality performance similar to that offered with the use of the PWFS2.
