Interstellar Medium Absorption Profile Spectrograph
The Interstellar Medium Absorption Profile Spectrograph
(IMAPS) obtained high resolution (R=75,000 for IMAPS-1)
echelle spectra of hot stars, over the spectral region
The Principal Investigator was
Dr. Edward Jenkins from Princeton University.
IMAPS was one of 3 spectrographs comprising the ORFEUS-SPAS mission.
The ORFEUS-SPAS platform was deployed from the Space Shuttle Discovery
in September, 1993
and from the Space Shuttle Columbia in November, 1996. The IMAPS archive
currently contains roughly 600 spectral images of 10 hot stars from
the first shuttle flight. The data from the second IMAPS mission,
an additional 3,900 spectral images of 29 stars, was never released
by the project.
