Notes. (a)Along the nominal Parker spiral. Since 2003 the viewing direction has changed four times a year (https://soho.nascom.nasa.gov/data/ancillary/attitude/roll/nominal_roll_attitude.dat). (b)Along the nominal Parker spiral. Since mid-2015 (after the superior conjunction), perpendicular to it.(c) Along the nominal Parker spiral. (d)Only wedges 3 and 7 were used. (e)Data product changed. Before June 14, 2021, CH F 3–4: 84–138 keV was used.(f)Side 4 is not used because it is blocked by the sunshield during the cruise phase. Side 3 is often excluded due to noise issues. (g)Only effective energies available.

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.
