The dataset contains 2''624 EL images of size 300×300 pixels. The pixels are stored as integers in the range 0-255. Each image is labelled with a cell type, mono or poly for mono-/polycrystalline, resp.), and, with a defect probability which can take one of four values 0, ⅓, ⅔ or 1. The defect probabilities are encoded as floats.
