Fig. 7
Radio spectral index distribution between 4.85 and 1.43 GHz in NGC 2976 (colours). Both maps of total intensity were convolved to a common beam of 152′′ (the beam is not shown). The contours represent the total power map at 4.85 GHz, their levels are: (−5, −3, 3, 5, 8, 16, 24, 32) × 450 (rms noise level) μJy/beam.
