| - | 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 Milky Way Imaging Scroll Painting (MWISP) project is an ongoing unbiased Galactic plane survey of 12CO(1-0), 13CO(1-0) and C18O(1-0) emission using the Superconducting SpectroScopic Array Receiver system on the Purple Mountain Observatory 13.7m telescope. |
| - | 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 survey covers the longitude range l = (-10°,250°) and the latitude range |b| < 5.°2 across the velocity range VLSR = (-130,130) km/s (**TBC**). The final survey will cover 2600 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 the original data cubes was σ(T) ~ 0.8 - 1K. | + | The intrinsic angular resolution of the MWISP survey is ~50 arcseconds and the velocity resolution is 0.16 km/s for 12CO(1-0) and 0.17 km/s for 13CO(1-0) and C18O(1-0). The typical rms sensitivity per channel of the original data cubes is σ(T) ~ 0.5K for 12CO(1-0), and σ(T) ~ 0.3K for 13CO(1-0) and C18O(1-0). |
| - | CADE currently delivers 13CO(2-1) and C18O(2-1) integrated intensity and peak brightness maps of the full SEDIGISM region using the survey's public DR1. 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. | + | CADE currently delivers 12CO(1-0), 13CO(1-0) and C18O(1-0) integrated intensity and peak brightness maps of a 250 square degree pilot region described the initial MWISP survey paper (Su et al 2019, see below). To facilitate processing, the original WCS FITS data cubes were binned to 0.5km/s prior to the generation of the HEALpix moment maps delivered by CADE. |
| - | Please contact us [[mailto:cade@irap.omp.eu|cade@irap.omp.eu]] if you are interested in HEALPix maps of the other molecular lines transitions surveyed by SEDIGISM, or if you require maps at a different angular resolution for your science. | + | Please contact us [[mailto:cade@irap.omp.eu|cade@irap.omp.eu]] if you require MWISP maps at a different angular resolution for your science. The spatial coverage of the MWISP maps delivered by CADE will be expanded according to future MWISP data releases. |
