Hemispheric contrasts in recorded volcanic explosivity are sensitive to temporal adjustment and missing VEI

eruptions_full.csv and eruptions_NG.csv are the fixed derived analysis tables.
source_catalogue/ contains byte-preserved source GVP worksheet and position exports.
The worksheet header is dated 24 April 2026; the position header is dated 29 April 2026.
Both headers identify 5.3.5. The workbook Info citation identifies 5.2.8; see SI S10.
GVP source: https://volcano.si.edu . Source catalogue credit: Smithsonian Institution,
Global Volcanism Program, Volcanoes of the World. Retain source attribution on reuse.

The derived analysis keeps catalogue inclusion. Nine nominal years precede 9700 BCE;
three have VEI and two enter the model sample. Source methods and date uncertainties
remain in the original worksheet. These tables retain source dates without recalibration.
The geological covariate assignments are frozen in eruptions_NG.csv; the supplied
source catalogue exports establish episode provenance, while the regressions reproduce
from the assigned table. SI S2 describes the spatial resolution and assignment rules.
