There are two identical telescopes on Gaia, with main mirrors of size 1.45 x 0.5 meters. So PSF (point spread function) of the telescopes is more elongated in the direction of shorter dimension. And the pixels of Gaia are manufatured rectangular because of this. | |

| Jun 21, 2021 at 15:28 | comment | added | Daddy Kropotkin | Great! I look forward to your questions. I found this quote in the paper by Lundl: "The full quadrupole model is used to study Gaia’s ability to detect the so far unobserved quadrupole gravitational light deflection by Jupiter." Finally someone said it plainly! ;) lup.lub.lu.se/luur/… | |
| Jun 20, 2021 at 6:04 | comment | added | uhoh | There are so many really interesting references to read here I will take a few more days to dig in. I generally delay accepting answers for a bit as it bumps the page back to the active question queue which usually helps some users to appreciate answers they may have overlooked earlier. Thank you very much! I think there are the seeds of a few new questions here but I need to do my homework first. | |

| Jun 15, 2021 at 23:03 | comment | added | Daddy Kropotkin | @uhoh My pleasure! They were interesting questions and I learned a lot, too. About question #1, I was hesitant to give a "yes" since you posed several questions whose answers range from "yes" to "no." About #2, I can say "no" since I've not found any such claims/data, but I'm not an expert in this field so I could be missing something. About #3, I can add a more direct "yes." I've been wondering about the "how far into the GR rabbit hole" bit and in principle one can carry out the calculation of the Crosta $et$ $al.$ paper (i.e., eq. 7) to higher terms in the parameterized post-Newtonian apprx | |

| Jun 15, 2021 at 1:38 | comment | added | uhoh | Thank you for your extensive and well-sourced answer! There is a lot to learn here and from your many linked sources. For question #1 about GAIA, "Has this been tried? Did it work?" is phrased to encourage two boolean-like "Yes" or "No" answers. I can't tell for sure if those are available here, it would be greatly appreciated if you could add a "Yes" or "No" for each. I'll comment about questions #2 and #3 later after my coffee kicks in. Thanks! | |
