![]() ![]() ITC performance: imaging calculations typically take 2-3s, spectroscopic calculations take 4-5s, and calculations with multiple IFU elements take slightly longer. Estimated accuracies will be posted as they become available. Only the facility instruments listed above are supported sensitivity tables are available for visiting instruments on the relevant web pages.Ĭaution: the ITCs make some assumptions about telescope and instrument performance and approximations for computational simplicity. There is a separate web form for each instrument. for definition of the astronomical source) and specific elements for individual instruments. The ITC is built around re-usable modules (e.g. Unavailable features are indicated by red crosses. Clicking on the calculate button will post the user-defined values to the servlet and create an output web page containing the results. to select the units for source brightness) and text boxes to enter numerical values (e.g. to choose between point or extended source), pull-down menus (e.g. Within the form, the desired characteristics are defined by selecting radio buttons (e.g. see the more info links within the form). There are additional help pages in each section that provide further information (e.g. The web form is divided into four sections: (1) the spatial profile, spectral shape and brightness of the astronomical source, (2) the instrument and telescope configuration, (3) the observing conditions and (4) methods of how the observation will be carried out and the results analysed. The Gemini Integration Time Calculator (ITC) consists of a web form in which the user defines the principal aspects of the observation and a Java servlet, resident on a Gemini Observatory computer, performs the calculation and generates the results. Note that official ITCs do not yet exist for 'Alopeke and Zorro as of 2022A
