<UmbralRaptop> nice
* UmbralRaptop thought that you were supposed to divide by flats? >_>;;
<iximeow> are you? i'm still doing everything by hand in paint.net..
<iximeow> i suppose division makes sense
<UmbralRaptop> At least that's what I picked up in instrumentation classes, not sure what paint.net supports.
<bofh> ohh so *that's* what flats are for.
<iximeow> paint.net supports: not much
<iximeow> dividing makes sense to adjust for uneven light gathering, and in retrospect what i'm using aren't quite usable for that anyway
<UmbralRaptop> bofh: yeah, illumination concerns are a bit more subtle than the way darks deal with noise.
<iximeow> (i took the telescope out of focus to try measuring just light pollution, hence subtraction)
<UmbralRaptop> yeah, less than entirely even illumination

<egg|zzz|egg> bofh: no, I'm just amazed at the ~modernity~
<egg|zzz|egg> bofh: they also have csv fwiw
<bofh> egg|zzz|egg: point, XML is actually unusual as heck for scientific formats.
<egg|zzz|egg> bofh: also I'm unsure about xml, but I'll probably take FORTRAN FORMAT over csv, csv is hell
<bofh> egg|zzz|egg: same
* UmbralRaptop 🔪 the snek language's built in CSV library
<UmbralRaptop> Also, why do I keep on finding hyperbolic trig functions in stat mech?
<bofh> egg|zzz|egg: CSV sounds simple at first and then you get something even slightly complex in it and OH GODS DO NOT WANT
<bofh> UmbralRaptop: differences of exponentials, which you get from your Boltzmann factors and what have you.
<UmbralRaptop> bofh: admittedly, yes.
<bofh> (also you get them everywhere in the simple systems you cover initially, such as Mean-Field Theory on the Heisenberg Ferromagnet or whatnot)
* UmbralRaptop pokes classical assumptions with a continuous stick
* bofh Wick-rotates UmbralRaptop
<UmbralRaptop> Obviously the the solution to the CSV problems is to use FITS tables.
<bofh> AAAAAAAAAAAAAAAA
<bofh> down that path lies madness.
<egg|zzz|egg> ah yes, the best format,
<bofh> [[Citation Extremely Needed]]
<bofh> :P
<bofh> s/Ex/Eggs/
<Qboid> bofh meant to say: [[Citation Eggstremely Needed]]
<bofh> anyway I should prolly add spaceflightnow data to Kountdown
<bofh> let me look up the entry format
<UmbralRaptop> FORTRAN tables : punch cards ∷ FITS tables : magnetic tapes
<UmbralRaptop> <_<
<bofh> Which sums up the silliness of FITS, since magnetic tape has no immediate layout forced onto you :P
<awang> UmbralRaptop: Is snek's csv library horribly broken or something?
<UmbralRaptop> awang: possibly. It seems to have problems writing more than 1 row at a time
<awang> Like writing multiple rows at a time to a file?
<awang> ...I thought file I/O would be done sequentially in most cases, right?
<awang> I guess unless you mmap'd the file, but that's starting to get out of my area of familiarity
