First Data Release of the ESO-ARO Public Survey SAMPLING—SMT “All-sky” Mapping of Planck Interstellar Nebulae in the Galaxy

We make the first data release (DR1) of the ongoing ESO Public Survey SAMPLING (this http URL). DR1 comprises of 124 fields distributed in $70^\circ < l < 216^\circ$, $-35^\circ < b < 25^\circ$. The 12CO and 13CO (2-1) cubes are gridded in $8"$ pixels, with an effective resolution of $36"$. The channel width is 0.33 km/s and the RMS noise is $T_{\rm mb}<0.2$ K. Once completed, SAMPLING and complementary surveys will initiate the first major step forward to characterize molecular clouds and star formation on truly Galactic scales.
