Technical question for RL...

Do you have any idea of the pixel size in Webb imagery, in arc-seconds?

Do you know what it is for the Hubble?

I would imagine in both cases the detector resolution is closely matched to that of the optical system. There's no point in making the pixel resolution greater than that of the optics.

    - What is "R=100"? - ER - 3/3/2022 4:39:16 AM
      - I believe it has to do with the spectrometer - RL - 3/9/2022 12:19:27 AM
        
        That seems reasonable. Thanks. - ER - 3/9/2022 1:03:05 AM
