The visible part (≈ 419-696 nm) of the multiline electronic-vibro-rotational emission spectrum of the D2 molecule was recorded with moderate resolution mainly limited by Doppler broadening of spectral lines (line widths FWHM less than 0.013 nm). After numerical deconvolution of the recorded intensity distributions and proper calibration of the spectrometer the new set of wavenumber values was obtained. It is shown that new data are significantly more precise than those available for visible part of the D2 spectrum. Final results are reported as a supplement in the form of an atlas divided into 158 sections (each section covers about 1.5 nm) containing pictures of images in the focal plane of the spectrometer, intensity distributions in linear and logarithmic scales and the table containing wavenumber and relative intensity values for 11941 spectral lines together with available and new line assignments for the D2 and HD molecules.
