Gas Slit Camera

Target entity: Gas Slit Camera
Context triple: [MAXI, hasInstrument, Gas Slit Camera]

• A. Grille spectrometer
  The Grille spectrometer is a spaceborne infrared spectrometer designed to study the composition and structure of planetary and Earth atmospheres by analyzing their emitted and absorbed radiation.
• B. Dall–Kirkham telescope design
  The Dall–Kirkham telescope design is a type of reflecting telescope that uses an elliptical primary mirror and a spherical secondary mirror to provide good on-axis image quality with relatively simple, easy-to-manufacture optics.
• C. Kast double spectrograph
  The Kast double spectrograph is an astronomical instrument used at Lick Observatory to obtain detailed spectra of celestial objects across two wavelength ranges simultaneously.
• D. Maksutov–Cassegrain telescope design
  The Maksutov–Cassegrain telescope design is a compact catadioptric optical system that uses a spherical primary mirror and a meniscus corrector lens to provide long focal lengths with well-corrected, high-contrast images in a relatively short tube.
• E. Baker–Nunn camera
  The Baker–Nunn camera is a specialized wide-field tracking telescope system developed in the mid-20th century for highly accurate photographic observation of artificial Earth satellites.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Gas Slit Camera
Target entity description: The Gas Slit Camera is an X-ray monitoring instrument used on the MAXI (Monitor of All-sky X-ray Image) mission aboard the International Space Station to scan and map X-ray sources across the sky.
