Sample profiles obtained from IMAGE demonstrating the use of the different conditions for Lpp detection (red dots): Each case a-f shows the original profile in blue and its average in black (upper left), condition 1 (upper right), condition 2 (lower left), and condition 3 (lower right). The red dotted lines represent the mean values for each condition, the red dashed lines the standard deviation 2σ(⋅) of conditions 1 and 2, and the orange dashed lines indicate the standard deviation 1.5 σ(⋅) of condition 3. The orange dots are the next local minima. Condition 3 requires that they are above the orange dashed line if they are outside of ℒ (indicated green).
