Spamming you all with what I do all day.

POPped 4: full spectrum, dred 0.8

I'm analyzing the electromagnetic spectrum given off by a planetary nebula, creatively called M2-31. This is me pulling up the spectrum and restricting it to the bit I want to look at, which is 7065-7075 Angstroms (edging into infrared).

I have to estimate the centre of the lines, how wide they are and the flux. That's all done from the XV stuff above. These estimates go into the Emission Line Fitting program:

> elfinp
ELFINP> ? c1:7068.94
ELFINP> ? c2:7069.46
ELFINP> ? w1:0.62
ELFINP> ? w2=w1
ELFINP> ? qelf
> elfopt


Number of non-linear variables: 4
VA04A MAXIMUM CHANGE DOES NOT ALTER FUNCTION

Theoretically, this should give me a good match to the graph on my screen. Or, since it;s an ELF program, Orlando Bloom. I'm easy either way.

Line Profile Centre Width Peak Flux Line Flux
1 1 7069.485 0.620 2.106E+04 1.390E+04
+/- nan nan NAN NAN
2 1 7069.498 0.620 -1.903E+04 -1.256E+04
+/- nan nan NAN NAN
3 1 6736.140 0.620 0.000E+00 0.000E+00
+/- nan nan NAN NAN
0(All errors are 68% confidence intervals)

Okay, so this run didn't actually work - it's producing 3 lines instead of two, and two of them don't have a positive flux. Got to try remodelling with three lines.

You hurt my brain.

[doyle_sb4.livejournal.com]

Yup. I have much spectra-induced pain, and I intend to spread it around.

[shadowlongknife.livejournal.com]

Ooh. Head go all 'splodey.

You're really Fred Burkle in a Doyle suit, arencha...?

[vic-amy-z.livejournal.com]

Owwww!

[crawls away into a corner and panics about being stupid]

[doyle_sb4.livejournal.com]

One day I will write the Ultimate Mary Sue fic about Fred at university.

[doyle_sb4.livejournal.com]

Heh. You should see me when people post these wonderful meta critiques on themes and structures in the Jossverse and character essays and things. I'm in the corner going "I like shiny things."

[sweptawaybayou.livejournal.com]

Dude.

*ouch*

Would you, um, like some bread or donuts or cake to go with that?

[doyle_sb4.livejournal.com]

Your icon makes me giggle.

[sweptawaybayou.livejournal.com]

*g*

Well, then. My work here is done.

::hugs::

Smart chicks are hot.

:D

:D *lick* (I'm so the dumb member of the department. Everyone else practically has to strap their extra brains to their torsos like in Dilbert, argh...)

[lynnenne]

We need to talk. I want to go back to school next September. I'm looking at either neuroscience or astronomy. I'd love to get your perspective on the latter, and I'd be very grateful if you would agree to a chat session. Could you please e-mail me to set up a time? My address is lynne86@hotmail.com.

Thank you!

I'm a Pharmacist/Compounder and that still gave me a brain wave. I think I've short circuited...

*pets her brain*

[doyle_sb4.livejournal.com]

Ooh, I live with two pharmacists (connorbeast and thecount_ha). So what's a compounder do, then?

(I was hopeless at chemistry at school. Good thing I didn't want to be a doctor, since you need an A at chemistry A-Level)

[preetybird.livejournal.com]

I hate chem with a passion, but since my mom is a pharmacist, I inevitably took the same route. Hence, chem is now part of my daily life and I must maintain and control my amount of barfage regarding the subject.

So what's a compounder do, then?

A compounder makes medicine. Like capsules, creams, and pretty much anything else. Since I've just graduated, I tend to shy away from really making anything, cuz it's scary, when you think about it. Add a bit too much of component X and you're juggling with someone else's life. O.O

[bandgeek.livejournal.com]

Hey. I like 'em smart, but sans extra squishy appendage. And hey, I'd bet you're the funniest member of the department. :)

OOO! EMS Analysis!!! I know what this is!!! ... ish.

I'm guessing M2-31 is item 31 on the updated Messier catalogue?
*goes to check Messier numbers on-line*
*doesn't find it*
*gives Messier-number-finding search engines the finger*

Planetary nebula - this would be a roughly spherical (or at least apparently circular) gaseous body within the general sphere of influence of our own galaxy? Or is it a more distant spheroidal galaxy that you would have to allow for a slight doppler-shift in? What's its NGC number?

I don't think much of the NCG item with my year of birth, NGC-1970. It's a galactic cluster but i haven't seen any good images of it online, even on the Hubble site. However, go to the year Star Wars was unleashed, and WOW!



That's nice! :)

[violethamster.livejournal.com]

Is it wrong that I look at that and go, ooh, purty? I wish it wasn't too late to change my major. Computer Science is teh boringness and pointlessness.

[captainlucy.livejournal.com]

Oh bumflaps! It didn't post! The dreaded red X!!!

Oh well, just visit http://antwrp.gsfc.nasa.gov/apod/image/ngc1977_aat.gif

[midnightsjane.livejournal.com]

AAAAAAHHHHH! I think I've gone blind. How do you do that?
Sorry :) I love looking at stars, and nebulae and stuff, but the thought of having to do the math and such is very scarey. I have much math phobia. You obviously have a very big brain.

*awaits this day*

[metalphoenix.livejournal.com]

You make me go "damn I'm dumb."

Then I stare some more and see "angstroms" the small small unit of measurement also used in bond length and still say "damn I'm dumb."

I wonder though, if I could hero-worship you because you do what I wish I could. *loves*

[doyle_sb4.livejournal.com]

It occurs that mailing from my uni address at the weekend wasn't the best idea... anyway, I'm going out tonight but I'll be online most of the afternoon (it's 2pm now). My MSN's doyle_thegoodfight@hotmail.com and AIM's doylesb4.

[doyle_sb4.livejournal.com]

Aww, pretty!

[owl]

Ah, dred and pop and push and all that stuff! How lovely and familiar! I always forgot to pop and push for the first week or so in labs, and hence lost lots of stuff, so frustrating. Pushing and popping, sounds like giving birth, doesn't it? ;)
