<WeylandsWings> like the definition of r_0 is the diameter of a circular area over which the rms wavefront aberration due to passage through the atmosphere is equal to 1 radian but i am not sure to go about the conversion to seeing which is FWHM
<raptop> Unsure, unfortunately
<WeylandsWings> other places say r_0 is s the size of an imaginary telescope aperture for which the diffraction limited angular resolution is equal to the resolution limited by seeing.
<WeylandsWings> like it seems like there should be a way to go back and dorth
<WeylandsWings> forth^
<raptop> There's some worrying stuff implied in diffraction limited seeing, how much light is in those outer rings / does it mess with the FWHM idea?
<raptop> Or can you just go "the rayleigh criterion is good enough"?
<raptop> ...wait, I'm silly. wikiality gives how to get the FWHM
<raptop> θ_FWHM = 1.025 λ/D https://en.wikipedia.org/wiki/Airy_disk so for r_0 as an imaginary telescope aperture this is easy enough
<galois> [wikipedia] Airy disk | "In optics, the Airy disk (or Airy disc) and Airy pattern are descriptions of the best-focused spot of light that a perfect lens with a circular aperture can make, limited by the diffraction of light. The Airy disk is of importance in physics, optics, and astronomy.The diffraction pattern resulting from a uniformly illuminated, circular aperture has a bright central region, known as the Airy disk, which […]"

* raptop falls over
* raptop stares at doable projects
* raptop stares at focus and/or motivation
<raptop> !8ball Learn how to do surgery from a colorless fermion?
<galois> raptop: yes
* raptop was joking! D:
<raptop> !choose the research group should have a wiki|this would just cause more computer administration problems
<galois> raptop: Your options: the research group should have a wiki, this would just cause more computer administration problems. My choice: this would just cause more computer administration problems
<SnoopJ> heh
<whitequark> raptop: i do not know how to do surgery
<whitequark> i have good friends tho
<raptop> ah
<raptop> Right, just things like an emergency root canal
<whitequark> yeah?
<whitequark> i still don't understand what about it impresses people so much
<raptop> hrm, probably something about having a bit of a different relationship with your body
