NIRSpec Operations

The operational aspects of JWST's NIRSpec instrument define how instrument-level capabilities can be applied for science. These features include target acquisition methods, dither/nods for each observing mode, and special considerations for science observations.

The JWST Near Infrared Spectrograph (NIRSpec) enables 0.6–5.3 μm spectroscopy at resolving powers of ~100, ~1,000, and ~2,700 in multi-object spectroscopy (MOS)integral field unit (IFU) spectroscopy, fixed slit (FS) spectroscopyand bright object time-series (BOTS) spectroscopy modes.  

These NIRSpec science modes include the following operational capabilities:
