This profiles have been measured in runs 12078 (target 4) and 12079 (target 3) by scanning along Z at 7 different points along X. The target thickness was measured by taking the average of the left and right arms counting rates. The plots for foil 3 and foil 4 show the rate distributions along the foils (Z) at all 7 locations in X, the average rate along Z (integrated over X) and the asymmetry between left and right arms depending on Z. Foil 3 demonstrates a large (about 20%) variation of thickness, while foil 4 is more uniform. The left-right asymmetry shows a small (about 0.5%) but similar systematics for both the foils.
