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.
