Observing with SCUBA-2

JCMT operates a 12-hour night, running from approximately 7:30pm to 7:30am HST. Earlier starts may compromise short-wavelength data. For observers particularly interested in good 450um focusing it is recommended start of shift is pushed back to 8:30pm.

Data Reduction

For best results use the latest Starlink software and rsync for updates.
To find out how old your starlink installation is type: >> cat $STARLINK_DIR/manifests/starlink.versio
For quicklooks download processed SCUBA2 data (per scan/night/project) from the Archive.
