Variable sorting criteria
Each instrument is assigned with an up-to-5-step rating, evaluated as a blend of several elements. For this particular Variable, the rating is driven by:
the observed solar area (disk only or disk + corona)
the spatial resolution.
RATING CRITERIA:
1
Disk + corona viewed, high spatial resolution
2
Disk only viewed, high spatial resolution
3
Disk + corona viewed, coarse spatial resolution
4
Disk only viewed, coarse spatial resolution -
