Evolution of the meridional and sagittal slope errors (FWHM) of the entire area of the crystal surface illuminated by white beam with increasing absorbed power of the monochromator crystal P and directly linked storage ring current I. Slope errors are calculated as the widths of the distributions [\Delta\alpha_{\rm{m}}(x)] = [\partial z(x,y)/\partial x|_{{y=0}}] and [\Delta\alpha_{\rm{s}}(y)] = [\partial z(x,y)/\partial y|_{{x = 0}}], respectively, thus along the centre lines in both directions.
