Reported quantities

No reproducible primary item count was exposed for the cataloged source version.

Counts retain their source-reported units. Additional rows can describe components, paired items, or derivative copies and are not automatically added to the primary quantity.

Access information and download

CLI

# Read-only preflight
eyehub download casia2_keratometric_astigmatism --data-dir ./data --dry-run --json

# Download, only when preflight reports supported behavior
