==== What can JWST resolve? ====

A [[ https://en.wikipedia.org/wiki/Jansky | Jansky ]] is 1e-26 W / m^2^-Hz. The Hz bandwidth can be estimated from the wavelength and wavelength window: Hz = c Δλ / λ^2^ .

Two pixels needed for Nyquist deconvolution of point spread function. 0.11 arcsecond (as) pixels means 0.22 as minimum for estimating size (more is better) A 100 AU round shell is 0.22 as across at 450 pc. The galactic disk is 300 pc thick, G stars
