     4738refined when data are collected over a two-theta range that extends to

     4742<B>Bragg-Brentano</B>, "Sample displacement" is usually refined and for low-Z

     4810    least one delimiter. The first column in the table is used to
     4811    look up PWDR entries where the initial space-delimited string
     4812    after the PWDR tag ("myfile" in "PWRD myfile AZM=180...") must
