- CND
- clumpy, but how clumpy?
- self-gravitating, n~10^8?
- examine small-scale structures in CND
+ clump-size power spectrum
- Method description
- noisy image: difficult to fit
- smoothing bad: spectral resolution varies across OSIRIS field
+ really, really ugly spectral resolution map
- Smoothing "during fitting"
- GOAL: maps of velocity, width, density
+ similar to deconvolution
- decomposed into linewidth, centroid, and amplitude
+ High, narrow peaks
- Result
- HII / H2 decorrelated
+ BrG traces low-H2 regions
- thin filaments with narrow line widths
Questions
- Q Farhad: Any asymmetric velocity profiles towards positions, i.e. outflow signatures?
- A: No asymmetry noted.
- Q: How unique is the solution?
- A: If S/N good, fairly unique
