Thirty figures made by diff-ref-struct's own pipeline from the files in renamed/: fifteen projections with hidden lines and fifteen maps of the intensity on the temperature–2θ and time–2θ planes. The projections: the 19 long scans against temperature, all 100 scans against time, and the 39 scans of the 1270 °C hold against time into it; each over 0.5–27° and in four 2θ windows. Every curve is a scan as the beamline reduced it; every character is typeset by LuaLaTeX in Latin Modern; every caption below is the one written with the figure. Temperatures are nominal set points (F07). The two stages they show are F09.

The 19 long scans against temperature, 0.5–27°. Sample 400_4 (ESRF ID22, 10–11 June 2026, proposal HC-6528): the 19 long scans, from 900 °C (front) to 1300 °C (back), as a projection with hidden lines over 0.5–27° in 2θ; each pattern is moved by 0.3° to the right and 120 counts up from the one before. The patterns are the beamline's reduced files as received (intensity in counts after its normalisation, which makes every scan's integral the same); the first 0.5° (beamstop shadow and direct beam) is left out. Temperatures are the nominal set points typed into the scan names; there is no thermocouple record in the files. Fourteen scans are the heating ramp in 25 °C steps (900 to 1225), one more at 1225 and two at 1240 close the ramp, and the scans at 1290 and 1300 are the long exposures taken after the time series at those temperatures. The pattern is nearly featureless to 950 °C; broad maxima appear at 1000 °C and stay to 1240 °C; the two back patterns show the sharp reflections that grow from the 1270 °C hold onward (the hold itself is in the next figures).ramp-full · projection · PNG · PDFThe long scans, window 5.4–6.2°.

All 100 scans against time, 0.5–27°. All 100 scans with the sample, against time since the first scan (18:09:48 on 10 June 2026, front) to 10.0 h (the closing long scan at 1300 °C, back), as a projection with hidden lines over 0.5–27°, each pattern moved by 0.06° and 30 counts from the one before. Time runs on the oblique axis; the temperature programme behind it is: the ramp 900 to 1225 °C in 25-degree steps during the first 3.1 h, short scans every 262 s at 1240, 1245 and 1250 °C to 4.5 h, the hold at 1270 °C from 4.6 to 7.4 h, then 1275, 1280, 1290 and 1300 °C to the end. Long scans (19) and short scans (81) are drawn alike: the reduction normalised their integrals. The sharp reflections start during the 1270 °C hold and grow to the end; the broad maxima of the first stage are visible from about 0.9 h (1000 °C). Scan 085 (8.8 h, 1290 °C) has a relative error well above its class and is included as measured.all-full · projection · PNG · PDF 12.5 MB in drs/Publish/esrf-series/, not copiedAll scans, window 5.4–6.2°.

At constant nominal temperature the sharp reflections of the second stage appear and grow throughout the hold while the broad maxima of the first stage remain: the natural dataset for the kinetics of the transformation.

One scan per nominal temperature, 25 rows from 900 °C (bottom) to 1300 °C (top): the long scan taken at each temperature where there is one, else the last scan of its series; each row spans the midpoints to its neighbours, so the 25 °C steps of the ramp are tall rows and the 1–5 °C steps between 1240 and 1300 °C narrow ones. 2θ from 0.5 to 27° on a 0.01° grid (the files' 0.001° points averaged ten at a time by the core); the intensity on a square-root colour scale, so that the weak broad maxima of the first stage show beside the strong sharp reflections of the second.
