Erratum: Transit spectroscopy with JWST: systematics, star-spots and stitching

We publish an erratum to the paper Barstow et al. (2015). Fig. 18 of the paper is incorrectly described as showing primary transit spectra of a true Earth analogue orbiting an M dwarf at 10 pc distance; in fact, this figure shows the case for a 2RE rocky super-Earth with an Earth-like atmosphere. The correct figure for the true Earth analogue is included here (Fig. 1). All conclusions in the original paper remain unchanged, as although the planet:star area ratio is four times smaller in the true Earth case when compared with the super Earth, the lower gravity of the planet results in an increased
