Slits

The available slits are shown in the following table. The slit widths are given in pixels and arcsec projected on the sky. The spectral resolution is lower in a wider slit (see the grism table), even for point sources since under most atmospheric conditions the seeing wings of pointlike objects fill the wider slits. Note that for each f/6 slit width, 2 slits are available, one of which is offset from the optical axis and causes the spectrum to be shifted to shorter wavelengths on the array. Note also that the f/32 10 pixel wide slit and the f/6 2 pixel wide slit are the same slit.

Observation Preparation

This section focuses on how to prepare NIRI observations for your Phase I and Phase II submissions. Preparing observing sequences involves much more than setting up the observation of the target; the complete observing sequences must include in addition "acquisition observations" (e.g., for finding the target and centering it on the image ) if needed, observations of telluric standards and/or flux standards, and usually includes flat field calibrations and dark frames.
