**Definition:**

The residual [sum av|del(I)| / sum |av(I)|] for symmetry-equivalent reflections used to calculate the average intensity av(I). The av|del(I)| term is the average absolute difference between av(I) and the individual symmetry-equivalent intensities.

The permitted range is 0.0 -> infinity

**Type:** numb
