Due to technical issues UHRF is unavailable for use in 2015.
UHRF is an Echelle spectrograph located at the coudé focus of the AAT. It offers ultra high resolution of up to 1 million over very small spectral regions. An image slicer is used. Focal reducing lenses are available to provide lower resolutions. UHRF shares hardware components with the UCLES spectrograph.
