  skos:definition """The Arizona Imager/Spectrograph (AIS) consisted of five grating
spectrographs (with 9 channels) and 12 imagers packaged together for
observations at ultraviolet, visible, and infrared wavelengths. The
AIS is a unique combination of spectrographs and imagers designed to
measure the entire spectrum from 115 to 1100 nm with a spectral
resolution range between 0.2 and 0.8 nm to resolve rotational lines in
most vibrational bands. The coaligned imagers provided spatial images
of a few prominent spectral features at selected wavelengths. Spectra
and images of short-lived or rapidly changing events were obtained
simultaneously. The use of two dimensional intensified CCDs as
focal-plane detectors resulted in a state-of-the-art, highly
miniaturized instrument capable of spectral and spatial mapping of
targets.
Although it was designed for specific scientific objectives (e.g., the
study of shuttle glow), its versatility allowed the AIS to be used for
numerous other experiments such as studies of airglow or aurora. Small
changes, such as modifications to foreoptics and the replacement of
interference filters, could allow the design to be used in any number
of applications.
The experimental objective of the AIS was the multispectral and
radiometric measurements of: (1) orbiter plumes, (2) Earth limb, (3)
chemical release, (4) orbiter environment, (5) gas release, and (6)
calibration sources. The AIS experiment was unique and succeeded in
meeting its objectives even though the full potential of the
experiment was not fully realized. A review of the science data
resulted in the identification of about 40 sequences in which good
data were recorded on a variety of subjects."""@en ;
