Results of the fibre-internal measurements of the 100-mm fibre. The distribution of FTR and Gaussian centroid \(\mu _\text {F}\) provide information about the local DOI resolution of each irradiated DOI position. a FTR, Gaussian centroids μF of the TOF histogram fit and local DOI resolution with respect to the irradiated DOI. Linear fit is added to guide the eye. b DOI-specific FTRs plotted with their Gaussian fits at their centroids μF within the 100-mm fibre allow conclusions to be drawn about the DOI resolution
