Description:
Ophiuchus North-West (including cores A-I) mapped in Sub-millimetre continuum 850 micron. The observations were obtained with SCUBA in fast-scanning mode at the JCMT during March-June 2003. Additional sections of the cloud are still be be observed/processed. Flux units are in Jys per 15 arcsecond beam.
