Table 1.
High-level characteristics of the NIRSpec IFS mode.
| Field of view | 3.1″ × 3.2″ |
| No. of slices | 30 |
| Spaxel size (1) | 0.103″ × 0.105″ |
| Wavelength range (2) | 0.6–5.3 μm |
| Spectral resolution | ≈100, 1000, or 2700 |
Notes. (1)Defined as (slice width × pixel size). (2)For the NIRSpec gratings, coverage of the full wavelength range requires multiple exposures with different combinations of grating and filter (see Table 3 for details).
