Notes. The Type column indicates the source of the data: E (external), PI (XXL PI), and whether the observations are conducted in survey mode (S) or using target XXL sources (T). The Status column indicates whether the observations are completed (C) or on-going (OG). More detailed information, maps, and references are available at
