Note: Solar Monitor's coronal hole segmentations are performed by CHIMERA, a copy of which is available at: github.com/TCDSolar/CHIMERA.
The operations of the CHIMERA algorithm is described in a peer reviewed paper: arxiv.org/abs/1711.11476.
An extensive copy of coronal hole properties are available at: solarmonitor.org/data.
The latest positions of the coronal holes are given in heliocentric co-ordinates, and the region positions are valid on 9-Feb-2021 20:30 UT .
