This catalog was published by Kraemer et al. 2002. It includes all sources observed by the Short Wavelength Spectrometer aboard ISO using observing template AOT1.
Column Contents (some notes apply only to the ASCII version) 1 name (Greek letters spelled out, note 'mu' and 'nu') 2 TDT number 3 RA (J2000) 4 Dec (J2000) 5 infrared spectral classification (defined below and in paper) 6 notes (defined below and in paper)
Level 1 classes are based on the overall shape of the spectrum and thus the temperature of the dominant emitter.
1. naked star 2. star associated with dust 3. warm dusty object with little or no stellar contribution 4. cool dusty object 5. red spectrum rising to 45 um 6. no continuum 7. flawed spectrum
Level 2 classification identifies the dominant spectral features with 1-3 letters.
CE carbon-rich dust emission, dominated by SiC at 11.5 um CN carbon-rich proto planetary nebula CR reddened continuum from amorphous carbon CT carbon-rich spectrum showing the 21 um feature E emission lines are the only significant spectral feature F featureless (Groups 4 and 5) M miscellaneous N naked star, no molecular bands (Group 1 only) NO naked star with oxygen-rich molecular bands (Group 1 only) NC naked star with carbon-rich molecular bands (Group 1 only) NE naked star with emission lines (Group 1 only) NM a miscellaneous group of naked stars (Group 1 only) PN planetary nebula, many emission lines PU as PN, but with UIR features SA oxygen-rich dust, 10 um silicate absorption SB oxygen-rich dust, self-absorbed silicate emission at 10 um SC crystalline silicate emission, especially at longer wavelengths SE oxgyen-rich dust emission at 10-12 um Group 2.SE is subdivided as follows: 2.SEa broad low-contrast dust feature from alumina 2.SEb structured silicate emission 2.SEc classic narrow silicate emission SEC crystalline silicate emission at 10-11 um and to the red U UIR emission features dominate the spectrum W spectrum peaks 5-8 um, drops to red, many are WR stars C/SE silicate/carbon stars C/SC mixture of carbon-rich and crystalline silicate features U/SC mixture of UIR and crystalline silicate features Suffixes: e emission lines p peculiar u UIR features present : uncertain classification :: very uncertain classification
Key to notes:
F quality flag such as pointing or telemetry problems G extragalactic source W wrong coordinates; o: probably an off, but odd in some way R, R: possibly a recoverable group 7 H probably irrecoverable in group 7 Offset name includes offsets from nominal position indicated by (0,0) Propn name from original observer
