Abstract

We report accurate new wavelengths for 29 mid-infrared ionic fine-structure lines, based on observations with the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO). Our results originate from observations of NGC 7027, NGC 6543, NGC 6302, the Circinus galaxy, Sgr A West, and W51 1RS 2. The obtained accuracies (λ/Δλ) range from 3 × 10 4 to 1 × 10 5 , depending on instrumental mode and uncertainty in radial velocities. © 1997. The American Astronomical Society. AH rights reserved.
