Bragg angle: operational definitions
Parrish, W., Wilson, A. J. C. and Langford, J. I.  International Tables for Crystallography (2006). Vol. C, Section 5.2.1.4, pp. 491-492 [ doi:10.1107/97809553602060000596 ]
... definitions The Bragg angles are determined from the observations by a series of operations that are often quite complex. For film cameras of diameter 57.3 or 114.6mm, a simple measurement with a millimetre scale gives [theta] in degrees (1mm = 1 or ...

Errors of the Bragg angle
Parrish, W., Wilson, A. J. C. and Langford, J. I.  International Tables for Crystallography (2006). Vol. C, Section 5.2.1.3, p. 491 [ doi:10.1107/97809553602060000596 ]
... but the systematic errors will affect all measurements consistently to a greater or lesser extent. The systematic errors may be, and ... consistency: the values of the apparent lattice parameter, plotted as a function of [theta], would show a systematic drift, not a random scatter. The success or ...

Errors and aberrations: general discussion
Parrish, W., Wilson, A. J. C. and Langford, J. I.  International Tables for Crystallography (2006). Vol. C, Section 5.2.1.2, p. 491 [ doi:10.1107/97809553602060000596 ]
... The lattice spacing d is related to the lattice parameters a, b, c, [alpha], [beta], [gamma] and the indices of reflection h, k ... the simple case of cubic crystals, the relation is where a is the single lattice parameter. The general relation is ...

The techniques available

... More details of systematic errors in diffractometry are given in Wilson (1963, 1965c, 1974). Some general points on checking precision ... the purposes of this chapter is angle-dispersive diffractometry with a conventional tube source (1).
