Note that many of the Optional Parameters have default values; in such cases, an Optional Parameter entry in the Visit and Exposure Specifications is necessary only if it is desired to override the default value. In the STScI proposal system the physical units of Optional Parameter quantities are always implicit and should never be entered by the observer.Optional Parameters whose descriptions begin with the phrase “USE WITH CAUTION” pose a risk to the intended science if a non-default value is used inappropriately. These parameters are italicized in Table 10.1. You may wish to discuss the use of these parameters with your Contact Scientist, if you have one, or with an Instrument Scientist via help@stsci.edu.Please note that spatial scans are not permitted with the FGSs. Also note that only FGS1 will be calibrated as a science instrument for Cycle 20.Table 10.1 lists the permitted Instrument Configuration, Operating Modes, Fields of View, Spectral Elements, and Optional Parameters for the FGS.
