Figure 8
Close-up illustration of the 211 peak fitting result for `live' measurement in blue and stationary measurement in red. The peak intensities are normalized so that they have the same intensity height distribution. The peak positioning error for the stationary measurement is 30 p.p.m. and for the `live' measurement is 50 p.p.m. The measured compressive strain (630 microstrain) represented by the peak shift is highlighted in light grey colour and the peak positioning error margins are highlighted in dark grey colour. [See also the supplementary figure, which shows a mosaic of the engine cross section assembly at 120° crankshaft rotation (inverted greyscale colourmap).] |
