This package contains the three original numerical tables, RDCalc's JSON
subsets, provenance manifest, and conversion script. The entire data adaptation
and conversion script are available under GPL version 3; see LICENSE.txt for
the complete terms, including the absence of warranty. You may copy, modify,
and redistribute the covered material under that license, including for
commercial use. RDCalc's service restrictions do not override those rights.
WHO has not endorsed RDCalc. No WHO logo or chart artwork is included.

Changes made by RDCalc on 2026-09-21
----------------------------------
weianthro.txt -> data/who-weight.json: keep sex, age, l, m, s; days 0-730.
lenanthro.txt -> data/who-length.json: keep sex, age, l, m, s; days 0-730.
wflanthro.txt -> data/who-weightLength.json: keep sex, length, l, m, s;
  all rows at lengths 45-110 cm.
Numeric JSON rows are [sex, age-days-or-length-cm, L, M, S]. Sex is 1 for male
and 2 for female. No coefficient rounding is applied. WHO's original files
under original/ are byte-for-byte unchanged, including their line endings.

Source and reproduction
-----------------------
All files are served beside this notice at /reference-data/who-2026-09-21/.
No account, subscription, or further permission is required to download them.
The manifest records the pinned upstream URLs, original file hashes, output
file hashes, and row counts. Download manifest.json, rebuild.py, LICENSE.txt,
DESCRIPTION.txt, README.txt, the three original/*.txt files, and the three
data/*.json files, preserving their relative paths. Then run:

  python3 rebuild.py --check

Python 3's standard library is sufficient. Omit --check to regenerate the JSON
files. This reproduces the exact bytes used by RDCalc, not clinical validation
of a different population or additional indicators.

Scope
-----
The numerical data package is separately licensed from RDCalc's independently
written application. No WHO R implementation or runtime is shipped in RDCalc.
This notice does not impose restrictions on scientific facts, mathematical
methods, or other uses that do not require copyright permission.

Availability
------------
RDCalc must keep this version's source and notices available with distributions
that use it. Future data updates should publish their own matching source and
transformation record, retaining access for versions still being distributed.
