The images folder contains RGB images of the whold DR1 region and RGB images of individual molecular clouds.

The RGB images of the DR1 regions contains two versions, the RGB map of integrated data and the l-v map of three CO lines. For the RGB map, we provide two versions in high resolution,  which are labeled and unlabeled by prominenent regions. For the l-v map we also have two version: (1) normal RGB l-v map three CO lines and (2) the 12CO l-v map with arm models overlapped.

RGB images of individual molecular clouds include 304 molecular clouds that have all 12CO/13CO/C18O emission detected by DBSCAN.
