The 4735 histogram scale factor is usually refined. 4736 For <B>Debye-Scherrer</B> mode the "Sample X displacement" 4737 is also ususally refined but the "Sample Y displacement" can only be 4738 refined when data are collected over a two-theta range that extends to 4739 greater than ~140 degrees (typically for CW Neutron). Sample absorption should not be 4740 refined when all atomic displacement parameters (Uiso or Uaniso 4741 values) are varied, as the correlation is very high. For 4742 <B>Bragg-Brentano</B>, "Sample displacement" is usually refined and for low-Z 4743 samples "Sample transparency" is usually refined. "Surface roughness" 4744 parameters are not usually refined. 4745 4746 Remaining parameters are of use for texture or parametric studies and 4747 may be changed with the menu commands described here. 4748 </p> 4749 4750 4751 <DL style='margin-left:1.25in'> 4752 <DT>Set scale</DT><DD>Rescales a pattern by multiplying by the 4753 current scale factor. 4754 </DD> 4755 4756 <DT>Load</DT><DD> 4757 This loads sample parameters from a previously saved .<span 4758 class=SpellE>samprm</span> file. </DD> 4759 4760 <DT>Save</DT><DD> 4761 This saves the sample parameters to a file with the extension 4762 ’.samprm’.

A header is not 4807 required. "Columns" in the table are separated by one or more 4808 delimiters (which may be a comma, tab or space). Note that columns 4809 do not need to be aligned, as long as each entry is spaced by at 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 4813 match the table.
