JAC Software Group
The JAC software group provides development and support to the UKIRT
and JCMT telescope operations.
Both UKIRT and JCMT use flexible scheduling to optimize scientific
returns of observing runs. Access the Observation Management Project (OMP)
site for information on observing projects. Information is available on
both the JCMT Observing Tool and the UKIRT Observing Tool
We write data in the flexible Hierarchical Data System (HDS) format
rather than FITS. Conversion tools are
We use the same generic data reduction pipeline on both telescopes in
order to provide near-real-time feedback to observers to optimize
flexible scheduling. ORAC-DR is
capable of producing near-publication quality results and is also in use
at the AAT and can support instruments from ESO and Gemini.
We support and recommend the Starlink software
applications. IRAF is also available.
Many of our data reduction applications were distributed by Starlink. However,
as the Starlink Project was terminated in June 2005, we have taken over
maintenance of the codebase. The Starlink Software Collection can now be
the Joint Astronomy Centre. The following JAC-supplied software is
distributed with the SSC:
- ORAC-DR - Generic data pipelining (both telescopes,
requires many other Starlink packages so usually best to install from
- SURF - SCUBA data reduction
- SPECX - Command line sub-mm spectral line analysis
- FLUXES - Sub-mm planetary fluxes (see also web interface)
They will work on Linux, Solaris and Mac OSX and, soon, Windows via
Cygwin. Historically, we have released bespoke reduction packages for older
instruments but these packages are no longer supported:
- Sub-mm continuum reduction of UKT14 and CBE JCMT data. (still useful
for archive processing). [Manual][Cookbook]
- Generic routines for infrared image processing. Now superceded by ORAC-DR and Starlink KAPPA.
- CGS4-DR - Monolithic application for analysing CGS4 data. Now
superceded by ORAC-DR and Starlink
KAPPA and FIGARO. Never
ported to Linux/G77.
Further information on reducing ACSIS data can be found in the ACSIS Data Reduction Cookbook.
A number of web applications are available to support your observing
