whitequark: there appears to be a trailing l at the end of the last observation in your latest lab note
<kmath>
<whitequark> @bofh453 Yeah but why is everyone making these contrived setups then
<egg|zzz|egg>
bofh: random thought: Adams nearly found Neptune before Le Verrier; this is the Adams from things like Adams-Moulton; are there integration methods discovered/rediscovered by Le Verrier?
<egg|zzz|egg>
(should I add Le Verrier to NewtonDelambreStørmerVerletLeapfrog or something :-p)

bofh: UmbralRaptor: "This success allows us to hope that after thirty or forty years of observations of the new planet, one will be able to use it, in turn, to discover the one that follows in the order of distances to the Sun. And so forth; one will sadly soon come upon invisible celestial bodies, because of their immense distance to the Sun, but whose orbits will end up, in the following centuries, being traced
<egg|zzz|egg>
with great exactness, thanks to the theory of secular inequalities."

egg|zzz|egg: what
<whitequark>
the chlorines aren't going to put themselves there on their own you know
<egg|zzz|egg>
!wpn whitequark
* Qboid
gives whitequark a treasonous enriched pounce
<Qboid>
egg|zzz|egg: I updated the explanation for EPIC
<egg|zzz|egg>
MAST?
<Qboid>
egg|zzz|egg: [MAST] => Mikulski Archive at Space Telescope
<egg|zzz|egg>
UmbralRaptor: the ProgName for the Spitzer observations backing "Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1" is RED_WORL
<egg|zzz|egg>
HAWK?
<egg|zzz|egg>
HAWK-I?
<egg|zzz|egg>
!acr -add:HAWK-I High Acuity Widefield K-band Imager
<Qboid>
egg|zzz|egg: I added the explanation for this acronym.
* UmbralRaptor
gives egg a 747-SP
<egg|zzz|egg>
bofh: UmbralRaptor: dug up the source data for the February 2017 Nature and May 2017 Nature Astronomy TRAPPIST papers, as well as Spitzer observing logs: https://photos.app.goo.gl/I6g10VHuxyUtk1s13
<egg|zzz|egg>
(caveat: the spitzer logs (shaded red) and K2 safe mode (shaded grey) are UTC whereas the transits are barycentric because I'm too lazy to do the conversion right now)
<UmbralRaptor>
hrm
<egg|zzz|egg>
UmbralRaptor: why the 747-SP?
<UmbralRaptor>
I thought HAWK was the name of a SOFIA instrument.
<egg|zzz|egg>
(yeah the backlog is long and full of catpics)
<UmbralRaptor>
egg|zzz|egg: obvious solution: use catterplot.
<egg|zzz|egg>
:D
<egg|zzz|egg>
UmbralRaptor: currently looking for VLT observing logs so I can mark those in the plot too :-p
<egg|zzz|egg>
(I may have nerd-sniped myself)
<UmbralRaptor>
egg|zzz|egg: If this reanalysis is sufficient for publication in that AAS notes journal, I'll be amused.
<egg|zzz|egg>
UmbralRaptor: tbh I'm not reanalysing anything, just plotting a pretty pic
<egg|zzz|egg>
(at some point I might make a principia initial state from the data though)
<egg|zzz|egg>
UmbralRaptor: they give error bars on the transit times in the Nature paper (not plotted my plot), but not in the data file for the Nature Astronomy paper...
<egg|zzz|egg>
(the K2 stuff)
<UmbralRaptor>
Ꙫ_ꙫ
<egg|zzz|egg>
UmbralRaptor: in the plots "curve. Each photometric data point is attached to a conservative error bar that accounts for the uncertainties in the detrending process presented in the previous section"
<egg|zzz|egg>
UmbralRaptor: so they don't have error bars for each point in the dataset like in the Nature paper (where the data came from many telescopes, with smol errors from Spitzer and big ones from the ground stuff)
<egg|zzz|egg>
wait no, the error bars vary quite a bit in the plot
<egg|zzz|egg>
how do they compute them
* egg|zzz|egg

\o/
<Ellied>
I would go for the full deletion but I've already removed all my important info from my account and have enough faith in my own self-control not to accidentally go back, so it seems like unnecessary hassle
<Ellied>
you have to put in an actual request to delete, apparently, which takes like 90 days to process
<egg|zzz|egg>
UmbralRaptor: hm so the Nature astronomy paper does give 1σ credible intervals on the transit times, but no idea what those are on the other K2 transits in their dataset
<egg|zzz|egg>
UmbralRaptor: grumble, am I going to have to work from the light curves
<egg|zzz|egg>
