afsis {powdR}

Africa Soil Information Service (AfSIS) XRPD reference library

Description

A powdRlib object of 21 pure reference patterns and associated reference intensity ratios for a range of common soil minerals. Data were collected on a Bruker D2 Phaser using Cu K-alpha radiation. All patterns have been normalised to 10,000 counts and reference intensity ratios transformed so that all are relative to that of corundum.

Usage

afsis

Format

A powdRlib object of 3 components

xrd

A dataframe of all the count intensities of all reference patterns. Column names denote the unique phase ID of each reference pattern

tth

A vector of the 2theta scale for all reference patterns in the library

phases

A dataframe the phase IDs, names and reference intensity ratios (RIR)
