CH properties extracted by CHIMERA.
|Nt||Coronal hole identification number for time t. This ID number is assigned in descending order of size.|
|X/YcenN||Coronal hole centroid coordinates in arcseconds and Stonyhurst heliographic coordinates.|
|X/YextentN||Most Eastern-Western/Northern-Southern positions in arcseconds.|
|Δθ||Longitudinal angular extent of the coronal hole in Stonyhurst heliographic coordinates and absolute degrees.|
|Atot,N||True coronal hole area. (ΣpixAcos,N)|
|A%,N||Percent coverage of the solar disk by the coronal hole area.|
|<Blos > N||Mean magnetic polarity along the line of sight.|
|Mean negative/positive magnetic polarity for a coronal hole along the line of sight.|
|Minimum/maximum magnetic polarity along the line of sight within coronal hole boundaries.|
|Absolute total polarity for all negative/positive pixels within a coronal hole boundary. ()|
|<Φ > N||Mean magnetic flux through the surface bounded by the coronal hole boundaries. (<Blos > NAtot,N)|
|Mean negative/positive magnetic flux through the surface bounded by the coronal hole boundaries. ()|
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.
