Figure 7
Impact of system thermal stability. (a) Magnified view of a composite RGB image showing the first and last diffraction images of the FF-LabDCT dataset, collected at nominally the same sample position, overlaid in different color bands. Green, magenta and gray colors represent the pixels present only in the first image, only in the last image and commonly in both images, respectively. The inset provides an even more enlarged view of the top spot. (b) Temperature profile associated with each diffraction image in the FF-LabDCT dataset. (c) Temperature profile and (d) spot shift distance (in pixels) for two example diffraction spots for a dataset collected at the same sample position over a long acquisition period. |
