The data acquisition and control systems for the William Herschel Telescope use a "mimic" display to present an easily assimilated view of the status of the telescope, its instruments and detectors. This display is specified in a set of data files th

Methods of observing where the observer continually interacts with the on-line system do not always make optimum use of the time available. Given the increasing pressure on observing time, it is now being recognised that both advance planning and gre
