Seven EFE spectral diagrams which are related to different spectral states of ESO 243-49 HLX-1 using the BMC model. The data are taken from XRT/Swift observations related to different hardness ratios: left: HR < 0.03 (black, HSS), 0.03 < HR < 0.07 (bright blue, HSS), 0.5 < HR < 1 (pink, LHS); right: 0.1 < HR < 0.2 (blue, IS), 0.07 < HR < 0.2 (red, HSS), 0.2 < HR < 0.5 (orange, IS), HR > 1 (green, LHS).

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.
