The Infrared Spectrograph (IRS) provides low and moderate spectral resolution spectroscopic capabilities from 5 to 40 microns. Long slits are available in the low-resolution modules. The IRS also has peak-up capability to centroid on a target and place it on the desired IRS slit with higher accuracy than provided by the blind pointing of the spacecraft alone. The peak-up arrays (with spectral passbands centered on 15 and 21 microns) also provide an imaging capability in the wavelength range that falls between that covered by the IRAC and MIPS instruments, and as such may be of interest for imaging alone. We describe how to use the IRS spectrometer, including its peak-up targeting function and modes for peak-up imaging.
