- Utilized a gas scintillation proportional counter spectrometer on Spacelab 1.
- The instrument covered an energy range of 2-80 kiloelectron volts with 180 cm² geometrical area.
- Achieved an energy resolution of approximately 9% at 7 kiloelectron volts.
Main Results:
- Presented new spectral data from Cygnus X-3 and Centaurus X-3.
- Included novel observations of the Perseus cluster of galaxies.
- Identified spectral line features with unprecedented quality due to high energy resolution.
Conclusions:
- The Spacelab 1 spectrometer provided high-quality spectral data of cosmic X-ray sources.
- The instrument's resolution enabled detailed analysis of spectral features, advancing X-ray astronomy.
