Noise of the different datasets.
| σ (persistence threshold) | |||
|---|---|---|---|
| HCO+ (mJy beam−1) | H13CO+ (mJy beam−1) | Herschel (1020 cm−2) | |
| Combined | 6.78 (×6) | 6.86 (×6) | 5.22 (×3) |
| 30 m | 285 (×4) | 300 (×4) | |
Notes. The noise of the different CASCADE datasets is calculated as the standard deviation of the signal in the respective edge-masked last velocity channel. For the Herschel hydrogen column density data, the noise is calculated as the standard deviation of the signal in a 50 pix2 rectangle at a position with no significant source emission. In brackets, the multiplicator to calculate the persistence threshold used as DisPerSE input is shown.
