The Science Performance of JWST as Characterized in Commissioning by Jane Rigby et al. on Tuesday 22 November

This paper characterizes the actual science performance of the James Webb

Space Telescope (JWST), as determined from the six month commissioning period.

We summarize the performance of the spacecraft, telescope, science instruments,

and ground system, with an emphasis on differences from pre-launch

expectations. Commissioning has made clear that JWST is fully capable of

achieving the discoveries for which it was built. Moreover, almost across the

board, the science performance of JWST is better than expected; in most cases,

JWST will go deeper faster than expected. The telescope and instrument suite

have demonstrated the sensitivity, stability, image quality, and spectral range

that are necessary to transform our understanding of the cosmos through

observations spanning from near-earth asteroids to the most distant galaxies.
