PHerc. Paris 4, tracing w010-027: a thirteen-depth atlas of the title region (ink-reader responses at fixed depths)

Numerical maps of the response of a carbon-ink reader moved through depth across the region that follows the last paragraph of the July 2026 page of PHerc. Paris 4 (tracing 20260701183124-w010-027): store arc 215 to 408 mm, z 56 to 224 mm, read in 634 tiles plus two control tiles on known writing, at thirteen offsets from the traced surface (0, ±24, ±48, ±72, ±96, ±120 and ±132 µm). One float32 map per offset at the reader's 9.6 µm pitch (17,500 × 20,104 pixels) with the window count and the seam mask, the control-tile maps, 8-bit views at 19.2 and 38.4 µm per pixel, the coverage (636 of 636 tiles; 28,270 of 29,919 mm², 94.5 % of the declared target, read at every offset), an inventory and SHA256 checksums. START_HERE.md describes the files and how to open a place and a depth. No readable title has been identified in the reviewed places; the maps are released whole so that any place and depth can be inspected. Methods, readers, the six complete maps of the page and the reviewed depth series are in the companion repository.
