ODI Guide Star Tool Description

ODI Guide Star Tool is a simple, handy star tool in Java. ODI's design allows to compensate for image motion caused by atmospheric blur or tracking error. Such image motion correction is done in the detectors during an exposure. The appropriate correction is determined from the motion of bright guide stars; for a full correction for atmospheric blur, one guide star is needed for each 4'x4' patch. This amounts to more than 200 guide stars over the focal plane. The guide stars themselves are read out in video mode on some cells of the detector, i.e., the light has to pass any bandpass filter before being recorded! For smooth operations of ODI it is important that the guide star acquisition process will be automated with little or none user interaction. The ODI guide star prediction tool provides a service to the ODI control system to automatically select guide stars. Since the availability of guide stars determines the operational mode for image mode correction, it will be important for a scientist to check the possible guide star configurations before observing, or better, before submitting an observing proposal.
