title: Calibration and efficiency of the Einstein objective grating spectrometer.
abstract: The Einstein Observatory, a large satellite dedicated to x-ray astronomy, carried the first large x-ray telescope to be placed in orbit and an objective grating spectrometer with two sets of gratings. This paper lists prelaunch calibration results and describes the derivation of spectrometer efficiency and resolution. Several calibration spectra are shown, and theoretical grating parameters are derived from the calibration results.
