Attack of the ATA
Right. So. I’m about halfway into my weeklong stay at the ATA. Lonely weekend what with the … no one else being here. But it hasn’t been breaking, and I haven’t been bored. Would be nice to be not-working as … Continue reading
Back
Long weekend driving undergraduates down to Lick and showing them how to use the Nickel. It was fun, but driving to the top of Mt. Hamilton and back twice is a bit draining. But, while I’m not quite sure from … Continue reading

Defeat From the Jaws of Victory
Changed my ATA proposal somewhat significantly, then sent it off two minutes before the official deadline. My understanding is that since Geoff is traveling, the actual deadline is more flexible, but I figure that it doesn’t hurt to honor appearances. … Continue reading
I Proposed
As expected, not a lot of time to get things done today. But I managed to put together a draft ATA proposal. I really wish that I had a sense of whether it was any good at all — although, … Continue reading

No Way
Hey, awesome. I feel like I’ve done a lot today and it’s only 8 PM! Wowee! In particular, I just sent out an email to the ATA users list summarizing my results with the antenna gains. People seemed pretty interested … Continue reading
Told You So
Today 120 was bitten in the ass by IDL. Hah. It was segfaulting when trying to run certain graphical routines, apparently because of an abused XLib call that was recently fixed in X.org. Things worked for some people though, and … Continue reading

Blogging Like It’s My Job
Today was the first Star Formation problem set. Didn’t feel like it should have taken ~12 hours, but here we are. Sometimes that’s how things are. Thought it was a pretty good set, though there were some ambiguities / mistakes … Continue reading

At Strada
A lot of time taken up yesterday on miscellany, and not a lot of note accomplished. Decided that I didn’t have enough time to make it worth taking Galactic Dynamics this semester. Wrote my annual report today. Nothing too exciting … Continue reading

Briefly Noted, Again
Class and tea take up a lot of time on Thursdays. Spent the rest of my time trying to fulfill my Galactic Dynamics responsibilities. If tomorrow’s discussion isn’t really good, I’ll probably drop it; gotta prioritize, and I don’t find … Continue reading

Smokin’
Took care of a lot of odds and ends today. Did a little more analysis of ATA gains — swallowed my pride and used Gnuplot to make a histogram of the calculated antenna gains. Which at least had the useful … Continue reading

Oof
I have a feeling Tuesday nights are going to be long nights this semester. There are still undergrads up in the lab working on 120. This morning, I implemented sorta-correct aperture photometry and got a halfway-decent lightcurve. Noisy, to be … Continue reading
