<UmbralRaptop> /me ponders how to grab data out of an old scatterplot saved as a jpg
<SilverFox> pixels/unit
<SilverFox> how many pixels long is x number of units
<SilverFox> math is easy at that point
<SilverFox> doesn't catch overlapping ones, because they're not visually different, but if it's all you got it's all you got
<SilverFox> but watch out for jpg artifacting
<SilverFox> UmbralRaptop, can I see the picture?
<SilverFox> you'll get approximations at best, but country girls make do
<UmbralRaptop> The "points" are large enough that artifacting isn't a problem
<SilverFox> i'd recommend a simple bitmap solution and iterating through the pixels
<SilverFox> after you use paint to figure out how many pixels there are per unit
<SilverFox> or units per pixel
<UmbralRaptop> Probably "sudo apt install gimp" rather than paint
<SilverFox> I mean, sure
<SilverFox> if you're going linux
<galois> RuntimeError: No active exception to reraise (file "/home/snoopjedi/.sopel/modules/parse_urls.py", line 70, in get_title)
<SilverFox> oh that's easy peasy
<SilverFox> why the fuck galois throwing a shit fit though
<SilverFox> I assume those ranges are important though, but honestly with this little data you might as well do it manually?
<SilverFox> you would've already had all the data in the time we had this conversation
<e_14159_> That looks like a diagram on my work time.
* UmbralRaptop installs a spectrograph and an AO system on e_14159_
<e_14159_> That's going to be boring; it's mostly water.
<SilverFox> I was thinking your graph would have like, hundo points on it, not like, 12
<SilverFox> do you have more than just this diagram to go through?
<e_14159_> Unless you want to use me as a mount for those; I'm pretty sure I can't keep myself sufficiently stable.
<SilverFox> duct tape solves all problems
<e_14159_> Including me complaining, yes.
<UmbralRaptop> Also, you need to withstand ~25-50 mph winds
<SilverFox> lemme refer you to this chart https://i.imgur.com/MpBI29B.jpg

<SilverFox> or just stem stuff?

<UmbralRaptop> Hrm. One of these design studies wants 4-6 6 m telescopes (half in north, half in south), but eggspects 2x6 m in north and 4x4 m in the south.
<UmbralRaptop> By my count, the entirety of scopes between 4.5 and 7.9 m in diameter: MMT (N), Magellan 1&2 (S), ВТА-6 (N), LZT (N, probably dead), Hale (N, lolpalomar), LAMOST (N, may present political problems)
<UmbralRaptop> 8-13 m ones are more common o_O
egg|cell|egg has quit [Ping timeout: 190 seconds]
<SilverFox> doesnt the size of disc change the focal point and resolution?
<SilverFox> bigger ones having further focal points
<UmbralRaptop> s/13/12/
<galois> UmbralRaptop meant to say: 8-12 m ones are more common o_O
<UmbralRaptop> SilverFox: all other things being equal with no thermal or atmospheric considerations, yes
egg|laptop|egg has joined #kspacademia
<UmbralRaptop> In reality, the atmosphere makes getting below 1 arcsecond hard, and below ~0.5 entirely dependent on adaptive optics
<UmbralRaptop> You can also design for different focal ratios, and the big telescopes tend to be very fast. (f/4.0 at most)
<SilverFox> i mean, you want quicker to avoid smearing right?
<UmbralRaptop> Eh, good tracking can solve that.
<SilverFox> fair enough
<SilverFox> so if you have tracking to compensate wouldnt you want longer exposures so you see more stuff?
<UmbralRaptop> There's a reason all professional scopes used equatorial mounts until well into the 1970s
<UmbralRaptop> And yeah, longer exposures help with seeing fainter objects
<SilverFox> yeah see, im something of a scientist myself
