| - | Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium (SEDIGISM) was a survey of molecular lines in the 217–221 GHz range with the SHeFI receiver on the APEX telescope. The key spectral targets were 13CO(2-1) and C18O(2-1). Other detected transitions include H2CO, CH3OH, SO, SO2, HNCO, HC3N, SiO. The survey covers a longitude range l = (-60°,+31°) and a latitude range of |b| < 0.5°. The latitude range extends to |b| < 1° towards the Central Molecular Zone (CMZ), to b > −0∘.75 towards the Nessie filament around l=338°, and to b < +0∘.75 towards the RCW 120 region around l=348°. | + | Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium (SEDIGISM) was a survey of molecular lines in the 217–221 GHz range with the SHeFI receiver on the APEX telescope.

| - | The total survey area is 84 square degrees. The intrinsic angular resolution of the SEDIGISM survey was ~30 arcseconds and the velocity resolution was 0.25 km/s for 13CO(2-1) and C18O(2-1). The typical rms sensitivity per 0.25 km/s channel of these data cubes was σ(T) ~ 0.8 - 1K. | + | The SEDIGISM survey covers a longitude range l = (-60°,+31°) and a latitude range of |b| < 0.5°.
