lol IOP... they're taking our jobs! I work for the UofC Press, on peer review and production. My old boss just accepted a position at IOP in the states, I'm hoping to get headhunted by him eventually :D
You're probably right about the figures, but I'd rather not chance it. It'd be kind of a shitty thing to bring down the credibility of the AAS!

I was on peer review and development ("publishing editor") for Journal of Physics A. IoP in the US is in Philadelphia, right? I never got a trip there out of that job, but I did get ones to San Francisco, Pisa and Bangalore, so it wasn't all bad.
― caek, Tuesday, 6 November 2007 19:37 (sixteen years ago) link
As far as I know they're mostly in Philly, but the story is a new office is opening in DC, which is where my former boss is going.
Think I can get away with this one, though I am no physicist so I have no idea what it's about beyond pretty colors...

It's probably a galaxy cluster. Contours are probably the same object at another wavelength, e.g. X-ray, which is a good thing to look at clusters in. Distance scale is much too small for the Great Wall and too large for a nebula.

What is your model made of? What is it supposed to be used for when it works?
― El Tomboto, Wednesday, 7 November 2007 21:18 (sixteen years ago) link
I make models of disk galaxies. They are ones that happen to be oriented edge-on to us so they look more like http://en.wikipedia.org/wiki/Sombrero_Galaxy (but even more edge-on) than http://en.wikipedia.org/wiki/Messier_81. This makes it harder to work out whether they have spiral structure or bars than ones that are face-on, which you can just look at.
The idea is I take an image of the edge-on galaxy, add up the mass along the line of sight and predict how the stars in a perfectly asymmetric galaxy with that mass distribution would move. I then compare this to measurements of the stars movement (I will show these soon). If I can't get, e.g. model and data velocity-radius curve to match in the central region then I can conclude that the galaxy is not perfectly axisymmetric and probably has a bar. Another product of this fitting process is the mass-to-light ratio. If M/L > 1 then we either have stars heavier than our sun for the amount of light they produce -- or dark matter.
That is the big idea, anyway. In practice I end up doing things like what I've been up to for the past fortnight, which is basically dealing with a shortcoming of my data, which is good in some regards, but poorly calibrated. This involves futzing around with numbers until my lines match the lines for the same objects published by the big, very accurately calibrated surveys.
― caek, Wednesday, 7 November 2007 21:29 (sixteen years ago) link
^^^ example of comparing my the velocity curve of my mass models to the data. That's a pretty good fit. M/L is worryingly high, but I know why that is. I need to regenerate all these plots.

What do you use to make your figures, caek? I do a lot of work on graphics, mostly because it seems there is a sizable group of authors using plotting software that they wrote themselves, and the fonts and/or colorspace get messed up. Also, IDL can eat my balls.
― dan m, Wednesday, 7 November 2007 21:50 (sixteen years ago) link
I use IDL : (
― caek, Wednesday, 7 November 2007 21:54 (sixteen years ago) link
Ahahah I thought so! :) The big thing is that in my experience, IDL does not know the difference between RGB and CMYK. It may say it does, but it doesn't.
― dan m, Wednesday, 7 November 2007 21:55 (sixteen years ago) link
Pretty much all astrophysicists do. There are movements toward Python, mainly coming from the Hubble dudes, but there is an awful lot of entrenched code. I'm not convinced Python's graphics capabilities will make journals' lives a lot easier anyway, although it is a much nicer language.
I'm going to redraw my figures for publication in Illustrator. It's what Tufte would do.

Yeah, it has a very, very eccentric colour system, although in 1993 it was pretty amazing.
It is presumably why my pure white backgrounds come out off-white when converted to a GIF by Preview.app.

Working with your stuff in Illustrator is a good idea. Convert those fonts to outlines!

Well, that's obviously Fiscal Year 2001 (trade center, get it?), that ended on Sept 30th. That is why the difference on such a small graph is almost unnoticeable.

Some group placed little white flags on our quad, each for "at least" 5 Iraqis dead, and little red flags, each for "at least" 5 Americans dead, from the Iraq war. The red flags are mostly clustered in a tidy area in front of the sign with our school's name on it, and the white flags stretch on for several blocks. It is pressing my art buttons, my math buttons, and my social justice buttons all at the same time.
Here is the first flickr photo I could find of it.

What kind of chart would you use to show, say, technological lag?
eg. you want to show, visually, a timeline of when the 486 became standard, then the pentium, then the p2... and then show when your company adapted the 486, ten the pentium, etc... and dsplay how long each took?

― blueski, Wednesday, 12 March 2008 18:21 (sixteen years ago) link
xp: opportunity to procrastinate, yay. Two options.
One is to plot the year of release against the year of adoption. The further above the line y = x the points are, the later it was adopted. You'd probably label the points with, e.g. "Pentium" or whatever rather than just put crosses.
http://i50.photobucket.com/albums/f325/caek/Picture1-3.png
Another is to plot the lag before adoption (i.e. adoption - release). The further above y = 0 the later the adoption.

Uh, don't use Excel.
― caek, Wednesday, 12 March 2008 19:09 (sixteen years ago) link
Sorry. Actually, that should be pretty easy in Excel. Set up three columns of data:
1988 1998 1988 1992 1993 1992 1994 1995 1994 1995 1998 1995 1998 2000 1998 2003 2007 2003
Then plot column 1 (release) vs column 2 (adoption) as points and column 1 vs. column 3 (release again) as a dotted line.
That may be a retarded way of doing it in Excel. I haven't used it since the Pentium II.
