Solar Images and Spectra from the Solar Maximum Mission (SMM) X-ray Polychromator
Entry ID: SMM-07

[ Update this Record ]

Summary
Abstract: Data from the X-ray Polychromator (XRP) consist of photon counting
rates at selected X-ray wavelengths in the 1.4 - 22.5 A band from
detectors which are used in a variety of modes to build up solar
images with various spatial dimensions.

Approximately 100 GB of data have been returned by XRP during the
mission. XRP data are processed through several stages to yield image
and spectral data. A ... View entire text

Quality Logical_Consistency_Report:
The AVHRR sensor was designed to view cold space and one or more
internal warm blackbodies for each scan sequence while in orbit. In
general, radiometric calibration involves exposing a radiometer to
sources of radiation that have been calibrated against primary or
secondary standards and determining a ... View entire text
