1291<h1>Strain fitting of 2D data in GSAS-II</h1>
1292
1293<p class=MsoNormal>For this demo, data were collected with a MAR2300 area
1294detector at APS 1-ID-C with a wavelength 0.12398 Å (100<span style='font-family:
1295Symbol'>m</span>m diameter beam) from a 1.5mm square hot rolled steel test specimen;
1296the front surface has been dusted with some CeO<sub>2</sub> to aid in
1297calibration. Three images are used here; one is with no load on the sample and
1298the other two are with the sample under tension along the y-axis (vertical).
1299The loading will distort the steel (ferrite &amp; austenite) diffraction rings
1300and our purpose here is to characterize this distortion via a strain model by
1301B. B. He &amp; K. L. Smith (Adv. in X-ray Anal. 41, 501, 1997). Note that menu
