The distribution of male sex pheromones cVA and CH503 within one pair of intact six-day-old virgin D. melanogaster flies. The dataset was obtained by LDI-TOF MSI in positive ion mode. (a) A 2-D ion intensity map of cVA at m/z 349.6 ([M + K]+) with signal intensity displayed in voxel view and rainbow-color coded within a mass window of ±0.1 Da. (b) The observed mass shift of cVA represented as a 2-D ion intensity map in PlusMinus 1 color scale. (c) The mass shift correction of m/z 349.6 signal made after applying recalibration method. (d) A 2-D ion intensity map of CH503 at m/z 503.3 ([M + K]+) with signal intensity displayed in voxel view and rainbow-color coded within a mass window of ±0.4 Da. (e) The observed mass shift of CH5O3 represented as a 2-D ion intensity map in PlusMinus 1 color scale. (f) The mass shift correction of m/z 503.3 signal made after applying the recalibration method
