B/jcmt Jame Clerk Maxwell Telescope Science Archive (CADC, 2003) ================================================================================ The James Clerk Maxwell Telescope Science Archive Canadian Astronomy Data Centre < CADC (2003) > ================================================================================ ADC_Keywords: Observatory log; Infrared sources; Radio sources Mission_Name: JCMT Description: The JCMT Science Archive (JSA), a collaboration between the CADC and EOA, is the official distribution site for observational data obtained with the James Clerk Maxwell Telescope (JCMT) on Mauna Kea, Hawaii. The JSA search interface is provided by the CADC Search tool, which provides generic access to the complete set of telescopic data archived at the CADC. Help on the use of this tool is provided via tooltips. For additional information on instrument capabilities and data reduction, please consult the SCUBA-2 and ACSIS instrument pages provided on the JAC maintained JCMT pages. JCMT-specific help related to the use of the CADC AdvancedSearch tool is available from the JAC.
