The measurements Irene Urcelay-Olabarria proposed and took with Iñigo González de Arrieta and Mireia Sainz-Menchón at ESRF beamline ID22 (proposal HC-6528, sample 400_4), treated here by Josu M. Igartua so that the team can interpret them: a heating ramp in 25 °C steps, then time series at 1240–1300 °C with a scan every 4.4 minutes, 2.8 hours of them at 1270 °C, and an empty-capillary background; 10.6 hours of beamtime on 10–11 June 2026. The files arrived as bare three-column tables with every piece of metadata in their names. This site records how they were read, what was recovered from them, how the copies were named, and what the numbers and the figures already show (broad maxima from 1000 °C, sharp reflections growing from the 1270 °C hold). The originals are untouched; every copy is checksummed against them on every build.
The extracted folder had no read permission on any file. Once readable, the files turned out to carry nothing but numbers: 2θ in 0.001° steps to 27°, an intensity and its error. Everything else was recovered from the names and the file system: the order and the clock time of every scan (the modification times agree with the elapsed seconds to the second), the nominal temperature, and from the contents two exposure classes, a common intensity scale, and one anomalous scan. The copies in renamed/ are named so that a listing reads as the experiment: sequence, temperature, elapsed time, class.
