Abstract / Description:Abstract. Because of the high cosmic abundance of iron, data on Fe are of particular interest in astrophysics, whereas data on the neighbouring element Co with its lower abundance usually are not. However, we have recorded data on Co XI in order to improve an extrapolation towards the line strength of the prominent 'red iron' corona line of Fe X which has turned out to be difficult to measure in the laboratory directly. In addition, new data on the two longer-lived excited levels in the ground configuration of Co XIII corroborate by isoelectronic comparison earlier data on Fe XII.
