Extended atlas of LRS spectra from IRAS
Listed in IVOA Registry (Virtual Observatory)
We present an updated atlas of spectra from the Low-Resolution Spectrometer (LRS) on the Infrared Astronomical Satellite (IRAS), which took spectra from 7.67 to 22.73{mu}m with a spectral resolving power ({lambda}/{Delta}{lambda}) of 20-60.
Description
The updated atlas includes 11238 spectra, including 5425 spectra published in the original LRS Atlas, 5796 spectra published in three later papers, and 17 spectra previously available online but not published.
The updated atlas has significantly more sources close to the Galactic plane than the original atlas. We have applied an improved spectral correction to remove an artifact at 8{mu}m in the original database. While the IRAS mission flew over 40yr ago, the extended LRS atlas remains the single most complete database of mid-infrared spectra of nearby and bright objects in the Galaxy.
