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

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
