How to take the data home

You don't. Data is transferred automatically to the NOAO archive so you can download the data from there. All raw DECam data is processed by a Community Pipeline managed by NOAO and delivers reduced images (single and stacked) with astrometric and rough photometric solutions (see more detail in the NOAO Data Handbook). You will be contacted by e-mail by NOAO when your reduced data is ready for downloading. The process may take a few weeks after your observations are finished.
