Table 1. Experimental parameters of the differently prepared LiNbO3 crystals.
‘obs’ and ‘all’ correspond to observed [
] and all recorded reflections with intensity I; 
is the maximum diffraction angle, h, k, l are the Miller indices, R corresponds to the different quality parameters of the data sets {
considers the integrated reflection intensities while 
considers the estimated standard deviation (e.s.d.) values of the structure factors; Petricek et al., 2014 ▸}, μ is the linear absorption coefficient, T is the transmission of X-rays and 
is the volume of the investigated crystals according to the absorption correction.
