WebThe NIRSpec Fixed Slit Spectroscopy template is to be used for all observations using the fixed slit spectroscopy mode of NIRSpec, and this article describes allowed values for all parameters. Advice on how to choose values which optimize your science can be found in the NIRSpec Fixed Slit Spectroscopy APT Template article. WebThe slit and slitless modes have some operational differences. The LRS slit mode is suited to a broad range of spectroscopic observations and therefore supports a wider range of operational choices. The single slit is 4.7" long (3.18 mm; 42.7 pixels) and 0.51" wide (0.33 mm; 4.6 pixels).
