  This archive supplied 156 posterior spectrum files, quality flags, source headers, manifests, and extraction code. These fixed inputs enabled the two-visit CE/OE window range study in ds007176 under the stated eye-state mapping assumption.

• usesClosed eye alpha log power had greater covariance with its eye state log ratio within visits in two adult cohorts under source labels

  This study used the preserved ds007176 spectra, quality masks, source records, and extraction code. They supplied the second cohort and the G2 subset check.

  This prior test in a second source helped define the question for the new study. We tested the direction in alternating eye states during one visit. We used no participant outcomes from the prior test.
