An Improved Atlas of Full-Scan Spectra from ISO/SWS

Abstract

We present an atlas of full-scan spectra from the Short-Wavelength Spectrometer (SWS) aboard the Infrared Space Observatory (ISO) after reprocessing and improving an earlier version published 22 years ago. The SWS spectra cover the wavelength range from 2.35 to 45.3 μm. They include scans in 12 separate bands, and we have updated the methods used to combine those bands into a single continuous spectrum. The main improvement comes from applying multiple constraints, including new photometry and spectra from the Infrared Spectrograph (IRS) on the Spitzer Space Telescope that have become available since the release of the original products, and individualized attention to each spectrum, to renormalize the separate bands into a more consistent single spectrum. In particular this removed unphysical negative fluxes that were common in the original data products. The new database, with 1035 reprocessed spectra, will be available to the community at IRSA, which also hosts the original processing.

arXiv commentThe dataset is currently available via the Dataverse (https://doi.org/10.7910/DVN/VZRPWU) and will be hosted by IRSA
