Yeah, a cat is small enough that a straight through finder shouldn't be at a bad angle very often.
<egg|zzz|egg>
UmbralRaptor: well I'm probably looking at the same finder as in zurich but straight through (so 80 mm), so placement wrt the scope is unusual :-p

so my gas tank seems rather biased towards full, I can go further on the first quarter than I can in the 50% after that, and the final quarter lasts much less than a third of the first quarter, how would I express this mathemajically?

20:21:09 <@egg> so all the orbits are going to be articulated around some silly line >_>
<bofh>
seems... not unreasonable?
<egg>
UmbralRaptor: yeah at 0 which feels wrong?
<egg>
UmbralRaptor: phl got the inclinations from a paper that somehow lists inclinations but not nodes and i have no idea how they get the inclinations without nodes
<bofh>
I assume fixing the nodes at the same point?
<egg>
they menion the transit impact parameter b = a cos i/R*, so yes, but why
<egg>
on what grounds can you say that all the nodes are 90 deg away
<bofh>
/¯\_(ツ)_/¯
<egg>
this thing https://arxiv.org/pdf/1001.2010.pdf says "Since the orientation of the line of nodes relative to celestial north (or any other externally defined axis) is usually unknown and of limited interest, we might as well align the X axis with the line of nodes; we place the
<egg>
descending node of the planet’s orbit along the +X axis, giving Ω = 180 deg"
<egg>
so, um, no good reason >_>
<bofh>
"Since the orientation of the line of nodes relative to celestial north (or any other externally defined axis) is usually unknown and of limited interest" I mean I *agree* with them here.
<egg>
bofh: well it depends, if all the nodes are magically aligned it looks silly in KSP
<egg>
UmbralRaptor: bofh: so that means the inclinations given by fitting the transit widths are really minimal inclinations, since you'd get the same width from more inclination closer to the node?
<bofh>
Hrm. I *think* so?
<egg>
UmbralRaptor: bofh: so, should we randomize the nodes a bit, doing spherical trig to have the inclinations yield a consistent transit width, and then run the optimization with that fixed
<egg>
so that it doesn't look weird
* egg
ponders
<egg>
wait shouldn't the nodes precess anyway?
<bofh>
I mean they will in any natural orbital system...
<egg>
UmbralRaptor: we need planet-planet occultations!
<UmbralRaptor>
!
<egg>
UmbralRaptor: does randomizing the Ωs make sense in the meantime?
<UmbralRaptor>
I guess?
<egg>
UmbralRaptor: https://forum.kerbalspaceprogram.com/index.php?/topic/157020-seven-worlds-around-slippist-1-v04/ sounds like a good starting point as far as actual planets are concerned
<egg>
since we're using up fewer dof for the fit that's better than the best χ² they report in their paper!
