PIXIE measures the bremsstrahlung X-ray flux in two spatial dimensions and as a function of energy from 2 keV to 60 keV in 64 energy channels. The spatial resolution and sensitivity of the instrument are a function of orbital altitude. Sensitivity is optimized by the use of a variable configuration of the instrument's adjustable aperture plate. Continuous imagery will be provided, since PIXIE is mounted on the despun platform. Each X-ray photon is identified individually by the time and location at which it is detected within the focal plane. INSTRUMENT REFERENCES: 1.

KEY PARAMETERS DESCRIPTION: The Primary Key Parameter data consists of two 64x64 pixel X-ray image arrays and two Mean Intensity measures. The images and intensities are associated with two variable integrated energy channel ranges. The Secondary Key Parameter data contains information necessary to the appropriate interpretation of the images. This information includes geographic and geomagnetic spatial registration references, integrated energy range definitions, data quality flags, and various mode/state indicators. The spatial references include full pixel maps (providing the value of a particular coordinate, e.g., magnetic latitude, at each of the 4096 pixels) as well as simple pixel markers locating specific features (such as the geographic and geomagnetic poles). <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ POLAR_PIX_KP <_DOI>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/DOI.json <_AccessInformation>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/AccessInformation.json 1996-02-27T23:59:57Z 2008-04-04T23:59:57Z <_TemporalDescription>Generated from all.xml/@timerange_start and all.xml/@timerange_stop <_ObservedRegion>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/ObservedRegion.json <_ProcessingLevel>Processing level is not available in the master file; it should be there instead of, say, https://github.com/rweigel/cdawmeta-spase/blob/main/ProcessingLevel.json spase://SMWG/Repository/NASA/GSFC/SPDF Online Open SPDF/CDAWeb.
