In the version of the article initially published, in the “Space telescope orbit and attitude simulation” section of the Methods, the article assumed that the minimum Earth limb angle for ARRAKIHS was 7.6°, the same value as that of Hubble Space Telescope, while the angle adopted by the mission proposal is 55.7°. As a consequence, the satellite trail frequency per exposure, percentage of affected exposures, and area affected per image in the original version for ARRAKIHS would thus correspond to a Sun-synchronous terminator aligned telescope with an orbit altitude of 800 km, a 1.4 degree 2 field of view, and a minimum limb angle of 7.6° (now designated, “800 km SSTA”, see corrected Fig. 2 in the article).…
