CUBISMCUBISM, The CUbe Builder for IRS Spectra Maps, is a tool for constructing spectral cubes, maps, and arbitrary aperture 1D spectral extractions from sets of mapping mode spectra taken with Spitzer's IRS spectrograph. Developed by the SINGS team to fulfill, in part, its Legacy proposal commitments, CUBISM has been released and is available from the SSC. It is optimized for non-sparse maps of extended objects, e.g. the nearby galaxy sample of SINGS, but can be used with data from any spectral mapping AOR.
ReferenceThe algorithm and design of CUBISM are documented in the following paper:
Spectral Mapping Reconstruction of Extended Sources, J.D.T. Smith et al., 2007, PASP 119, 1133.
Please reference this paper for all scientific uses of CUBISM.
DesignCUBISM is divided into three main components:
- CubeProject: For organizing and interrogating input BCD's, setting up cube build parameters, and building the cube.
- CubeView: An all-purpose viewer for examining individual BCD's, editing the aperture over which cubes are built, navigating through spectral cubes plane-by-plane, extracting spectra from cubes over any spatial aperture, along with many traditional viewer features.
- CubeSpec: The viewer for extracted 1D spectra, permitting peak and continuum regions to be defined and line or feature maps to be created (with or without continuum fitting).
Parts of CUBISM derive from JD Smith's thesis work, and elements of SCOREX, a tool written for SCORE, the IRS Short-High Spectrograph proto-type instrument. CUBISM is written in IDL.
- July, 2011:
- A version of CUBISM (v1.8) compatible with the final IRS reprocessing pipeline (S18.18) has been released.
