2 shows the raw data and Fig. 3 shows how this is reconstructed at the telescope into a broad-band image to aid acquisition. Raw data for NGC7469. Comparison with Fig. 5, which shows a visible-red HST image of NGC7469 with the IFU field superimposed, suggests that the emission line ratio is highest near the nucleus and reduced in the starburst ring. However, at larger radius than Genzel et al. surveyed, we find that this ratio increases.
Dark colours indicate high intensity and high line ratio.
The nucleus is at the right-centre of the field. The image is on a logarithmic scale. The Durham AIG gratefully acknowledges the help and encouragement of the JAC in commissioning the instrument, in particular Gillian Wright and Tom Kerr. In Durham, we thank George Dodsworth, John Webster, Ray Sharples and David Robertson for engineering and programmatic assistance. We also thank Chris Done and Reynier Peletier in Durham for help with data reduction and analysis.
