All-sky composite map of the first two moments of the H i distribution using the same coordinate system and map projection as Fig. 2. The Moment-0 (the column density) determines brightness (log-scale), while the Moment-1 (intensity-weighted radial velocities) is encoded as different hues. The brightness is furthermore modified according to the velocity scale, to render the weaker intermediate- and high-velocity gas more visible. We note that radial velocities in excess of the displayed color scale are subject to clipping: the true radial velocities of red and orange features may be larger than what the colors denote.
