TW Hydra (ALMA versus SMA):
The ALMA data were taken on April 22, 2011 (Band 7 Science Verification data). There are approximately 1.9 hours on source and the channel width
is 0.106 km/s. The SMA data were taken on March 9, 2008 (PI: Sean Andrews). There are approximately 0.5 hours on souce and the channel width is
0.704 km/s in the CO(3-2) band. Note that the minor axes of the ALMA and SMA beams are similar (lower left). Both data sets were self-calibrated and
imaged using the CASA software package.
CO(3-2) Line Emission:
ALMA data (left). Contoured at 0.125,0.25,0.5,1,2,4,8 x 10% of peak in channel. SMA data (right). Contoured at
1,2,3,4,5,6,7,8,9 x 10% of peak in channel. The SMA channel map was made at the frequency of peak emsission.
Continuum Emission:
ALMA data (left). Contoured at 0.03125,0.0625,0.125,0.25,0.5,1,2,4,8 x 10% of peak. SMA data (right). Contoured at
0.25,0.5,1,2,4,8 x 10% of peak.
Additional ALMA CO(3-2) Line Emission, 2.7 to 3.4 km/s (one SMA channel):
ALMA data (left and right). Contoured at 0.25,0.5,1,2,4,8 x 10% of peak in channel. The two channels are adjacent.
