1. CARMA

2. CARMA 225 GHz map with 0.9’’ beam (C-array) 1’’ is not good enough! BN? source I

3. subarcsec resolution requires adaptive optics to correct for atmospheric blurring blobs of water vapor signal delayed to this antenna differences from optical or NIR adaptive optics water vapor fluctuations are the main problem time scales of seconds, not milliseconds no laser guide stars

4. paired antenna calibration (PACS) observe nearby calibrator at 30 GHz with 3.5-m antennas 3.5-m ant quasarscience target

5. paired antenna calibration in action

6. 1mm B-array map before/after PACS corrections

7. BN source I 229 GHz continuum map 0.15’’ resolution

8. a reminder: interferometer acts as a spatial filter

9. H recombination lines toward BN Rodriguez et al 2009 CARMA

10. CARMA SiO v=0 86.7 GHz, 0.4’’ res

12. SiO v=0 spectra suggest rotation about a NE-SW axis

14. CARMA SiO v=0 0.85’’ resolution
