Figure 1. SAURON observation of the barred Sa galaxy NGC 2273, based on two 4×1800 s pointings. The field-of-view is 49′′×44′′, with an effective spatial sampling of 0.′′8× 0.′′8. Left panel: reconstructed total intensity. Right panel: S/N-map, the S/N being integrated along the whole SAURON spectral range. Red corresponds to an average S/N≈50 per resolution element. Note the galaxy spiral arms, as well as the two vertical S/N jumps close to the middle of the frame and the irregular boundaries due to the merging process of the different exposures.
