<UmbralRaptor> egg: yet.
<UmbralRaptor> Do they have grants yet?
<UmbralRaptor> ;8ball Can the VLT be used as a single telescope?
<kmath> UmbralRaptor: Yes
<UmbralRaptor> iximeow: The 3.5 m telescope being the WIYN, and the dual 8.4 m being the LBT.
<iximeow> ah! i didn't think of any particular 3.5m
<iximeow> that's funny
<bofh> UmbralRaptor: isn't 3.5m ~HiRISE grade too?
<UmbralRaptor> HiRISE is 0.5 m
<UmbralRaptor> But, that's still the largest telescope outside of 0.9-1.1 au.

<bofh> UmbralRaptor: ah, right.
<bofh> I had somehow remembered it was x.5m & couldn't recall if x was 1 or 3. Apparently neither, it's 0.
<UmbralRaptor> bofh: my slightly odd phrasing is due to eg: Spitzer and Kepler are in earth-trailing orbits. And Herschel was put in one for decommissioning.
<bofh> wait, when was Herschel decomissioned?
<UmbralRaptor> (0.9, 1.4, and 3.5 m, respectively)
<UmbralRaptor> Uh, 2013 or 2014.
<bofh> also iirc Spitzer doesn't do visible light, only NIR/FIR?
<UmbralRaptor> Yeah, NIR. Arguably getting into MIR before its coolant ran out… a decade ago.
* UmbralRaptor grumbles about how NIR/MIR/FIR are poorly defined.
<kmath> <bofh453> "The 70µm detector uses gallium-doped germanium technology, and the 160µm detector also uses Ga-doped Ge, but with… https://t.co/vQshMn73oC
<bofh> it's literally engineering a bandgap via bruteforce
* iximeow fishes for MIR in the pacific
<bofh> also yeah, they really are. at least it seems people agree on what UV{A,B,C} mean.
<bofh> LOL
<UmbralRaptor> Мир! \o/
<UmbralRaptor> I mean, filters are *usually* well defined, but you can easily confuse eg: Sloan u, r, or i band with Johnson-Cousins U, R, or I band if you don't pay close attention to capitalization and/or context.
<UmbralRaptor> Also, I bet radio people hate that there's an IR K-band.
<bofh> I mean we're more mad about the 14 or so band classifications above UHF and how they're mostly sensible but proceed to go off the rails at some point in the band diagram.
<bofh> But TIL.

<B787_300> UmbralRaptor: why are you going to complain that a 3.5 m telescope is too small?
<UmbralRaptor> B787_300: Because despite looking at nearby stars, it mostly is. o_O
<UmbralRaptor> I'm working on simulations of possible exoplanet surveys with upcoming instruments, and we'd really like to get radial velocity precisions of 1-3 cm/s.
<UmbralRaptor> Assuming an instrument that is sufficiently low noise, we still need enough light that the photon noise is down in that range. This gives prohibitively long exposure times for many stars and telescopes.
<UmbralRaptor> (precision scaling with ~photons^-2 is sometimes annoying)
<UmbralRaptor> prohibitive being several hours or worse. @_@

<rqou> Ellied, bofh: why so much hate for NI?
tawny has joined #kspacademia
<bofh> rqou: use LabView for a bit and you'll understand.
<bofh> it's extremely comparable in ""quality"" to Vivado in... pretty much every aspect I can think of, actually.
<rqou> um, i did an internship at NI :P
<rqou> mostly not involving labview though
<bofh> ah. okay, in that case maybe the rest of their stuff isn't as bad.
<bofh> so as always with companies like this, NI's *hardware* isn't bad.
<bofh> their software is a flaming sack of donkey shit and that's putting it politely.
<rqou> oh yeah, i can believe that
<rqou> what's interesting is that dataflow-oriented programming can be a neat idea
<iximeow> bofh: Did You Know That SpaceX looks for labview experience among launch folks/ground engineers?

<SnoopJeDi> studying a part of photosystem-II in cyanobacteria with x-rays at LCLS
<SnoopJeDi> reaaaally clever droplet-on-tape methodology
<SnoopJeDi> that lets them do precision pump-probe + x-ray sorts of experiments with samples instead of the more familiar liquid-jet falling into x-ray
