Science data taken for:
2016-2-LSP-001 P0 RSS (x2) (Observing optical counterparts of transient objects)
2018-1-SCI-008 P2 RSS (Probing the winds from massive binary star supernova progenitors)

2018-1-SCI-015 P1 HRS (Characterising the host star and protoplanetary disk environment in nearby young star systems)
2018-1-SCI-023 P1 RSS (x2) (Star-formation history and chemical evolution of low surface brightness dwarf galaxies)
2018-1-SCI-007 P2 HRS (x2) (Measuring the orbits of double white dwarfs. @_sublunar_)
2018-1-SCI-005 P2 RSS (Lyman alpha halo around high-z quasars)
