Color image of the signal-to-noise map derived for the V500 data corresponding to the continuum emission of the NGC 5947 galaxy at the wavelength range between 4480 and 4520 Å, based on the rough estimation described in the text. The contours shows the intensity of the V-band image synthesized from the datacube, with the 1st contour at 1.5 × 10^-18 erg s^-1 cm^-2 arcsec^-2 (~23.5 mag/arcsec²) and consecutive ones with a step of 3 × 10^-18 erg s^-1 cm^-2 arcsec^-2.
