Qualitative illustration of the observational horizons of main-sequence spectral types assuming a sensitivity limit of KS = 28m with MICADO and the ELT. The vertical dotted lines show the distance moduli of regions that are important for studying the IMF in environments that are significantly different from the solar neighbourhood. The height of each bar corresponds to the cumulative fraction of all stars belonging to a specific spectral type.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
