DATA

What this site publishes

twelve datasets, 1169 rows in total, all under CC BY 4.0. Every count on this page is derived from the file itself at build, so a dataset that grows moves the number without anyone typing it.

  1. /data/outgassing.json 258 entries

    Outgassing rates by material, species and surface state, each under the source key it was read from, with the pumping time it was measured at and the readings the corpus declares in conflict.

  2. /data/pumps.json 206 models

    Validated pump models and their parameters, exported only where a quotation was verified word for word against a retrieved document. Every value names its source key and page.

    The Matter cards: family, sector, vacuum behaviour and the candidate property layer, each property carrying the key of the source it was compiled from.

  4. /data/brazing.json 64 material pairs

    Brazing pairs, fillers, process routes and the rules in force, with the expansion figures each joint carries on cooldown and the disagreements between documents.

    Residual gas analysis reference: the mass table, cracking patterns, diagnostic ratios and alert thresholds used to read a spectrum.

These datasets are compiled from the sources each value names. They are candidate figures, not certified ones: a value carries the key of the document it was read from so you can check it yourself, which is the whole point of publishing them. Source documents are not redistributed.
