====== SEDIGISM ======
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 transitions include H2CO, CH3OH, SO, SO2, HNCO, HC3N, SiO, but their detection is typically restricted to the densest regions.
The SEDIGISM 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°. The total survey area is 84 square degrees, and the observations cover the velocity range vlsr=(-200,200) km/s.
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 the original data cubes was σ(T) ~ 0.8 - 1K.
CADE currently delivers 13CO(2-1) and C18O(2-1) integrated intensity maps of the full SEDIGISM region using the survey's public DR1. To facilitate manipulating the data, the HEALPix maps are also delivered in NSIDE=16384 (no smoothing before).
/*To facilitate processing, the original WCS FITS data cubes were convolved to 33 arcseconds and binned to 0.5km/s prior to the generation of the HEALpix moment maps delivered by CADE. */
