No underlying-stock relationship is recorded for this film. This does not establish that its formulation is unique.

A solid connection establishes the stated relationship, such as a respool or family variant. It does not establish unchanged resolution, processing or coating generation. Dashed connections retain the identity uncertainty.

Results below use a 36 × 24 mm image area and ideal two-sample spatial sampling. Approximate graph readings retain their source process; a color-layer envelope is not an uncertainty interval.

Manufacturer-published input

Resolving power · 1.6:1

~22.1 MP

80.0 cycles/mm · 36 × 24 mm

Manufacturer standard processing; historical sheet or current regional webpage, as identified by source.

Calculation & units

MP = 36 × 24 × (2 × R)² / 1,000,000

Original unit: lines/mm. Assume resolving-power counts denote complete line-pair cycles. Fujifilm and Kodak source wording retained; do not silently conflate individual line widths with pairs.

Derivation: manufacturer published number. Formal uncertainty is not established for digitized curves.
