Observing 10/20

I don't have a better place to post this one, so here it is:

My automated fitter (Gaussfitting Cube Collapser) has come a long way. I now adaptively choose to fit 1, 2, or 3 Gaussian components to output to a data cube.

The purpose of that code is primarily to find a two-dimensional way to display information about the 3D structure, specifically about the presence/absence of outflows. Outflows will inevitably be confused with multiple velocity components, but they are also likely to be convolved with them.

Last month's observations in L111

Mapped sources:
SH 2-156 [no high resolution observations; covered by 1.2m CO 1-0 survey]
SH 2-157 Yancy CS 5-4 , CO, 13CO 1-0, CS 2-1 , HCN & SCUBA too....
IRAS 23151 (two pointings)

Unmapped:
BFS 18 = IRAS 23042+6000 = IRCO 859
Wu et al mapped this in CO 2-1 and detected no outflows. They used the NRAO 12m with a heterodyne array with very high Tsys ~700-1100K.

Observing run summary

3 nights of worse than grade 4 weather (tau ~.4, i.e. the atmosphere is nearly opaque) have given me a few interesting results.

1. Non-detections of CS 5-4 in a few bright BGPS cores. My best guess is that the pointing was off, though, because I definitely got down to a noise level around 50mK.
2. Lots of CO 2-1 mapping, 13CO/C18O too. That means I can now use this plot: http://dustem.astro.umd.edu/pdrt/co3221web.html to try to measure the incident flux.
3. I can't do homework at the summit. Maybe it's just that I can't do stellar structures homework, but I really am not processing this stuff well. Damn.
4. Running at altitude uphill is really, really hard. All the running I've been doing the past N months has not even come close to preparing me. Need to correct that...
5. "I am inappropriate." I probably violate a bunch of those rules... the important ones...
6. gotta get back to the mountains. Really. Seriously. OMFG.
7. ARGH those papers need writing! Lots of it!

For the next observing run, need the following:
1. Pre-prepared A3 rasters
2. Larger selection of summit music
3. Better sleep schedule preparation
4. More caffeinated drinks per night
5. Cloud cannons.
