Dataset: "Mixing Chemistry and Pigments: X-ray Fluorescence Spectroscopy as a Nondestructive Technique for Analysis of Pigments in a Painted Japanese Handscroll" ; F1907.375a, XRF 2018

Scanning x-ray fluorescence data and relevant photodocumentation images of a Japanese handscroll, The Miraculous Interventions of the Jizō Bosatsu (Freer Gallery of Art, Smithsonian Institution, Washington, DC: Gift of Charles Lang Freer, F1907.375a). Scans were performed in 2018 with a Bruker Tracer 5g handheld XRF. The XRF data provided includes x and y position and the fitted element intensities for relevant XRF peaks. Any negative intensity values have been replaced by a zero value. The scanner x,y are rotated compared to the image; transforming the data may be necessary for proper orientation (rotate 90 deg). The scanner x position has been shifted to account for scanner travel direction. Data location is described as the handscroll scene (S##), a sequential letter for the scan area within the scene (e.g., A = 1), with a descriptor (e.g., woman).<br>Only select scenes from the larger study are provided for use to accompany the publication: "Mixing Chemistry and Pigments: X-ray Fluorescence Spectroscopy as a Nondestructive Technique for Analysis of Pigments in a Painted Japanese Handscroll" by Kathryn L.

本数据集包含日本手卷《地藏菩萨灵验记》（The Miraculous Interventions of the Jizō Bosatsu）的扫描X射线荧光（X-ray fluorescence, XRF）数据及相关摄影记录图像，该手卷现藏于史密森学会弗里尔美术馆（Freer Gallery of Art, Smithsonian Institution, 华盛顿特区），由查尔斯·朗·弗里尔捐赠，藏品编号F1907.375a。

扫描工作于2018年使用布鲁克（Bruker）Tracer 5g手持式XRF光谱仪完成。本次提供的XRF数据包含扫描点位的x、y坐标，以及对应特征XRF峰的拟合元素强度；所有负强度值均已替换为0。

扫描设备的x、y坐标系与图像坐标系存在旋转偏移，为使数据与图像朝向匹配，需对扫描坐标进行90度旋转变换；同时扫描x坐标已根据扫描仪的移动方向进行了位移校正。

数据点位的标注规则如下：以手卷场景编号（格式为S##）、场景内扫描区域的顺序字母标识（如A对应第1个区域），以及区域描述词（如女性）组合而成。

本数据集仅提供原研究中的部分场景数据，用于配合以下学术出版物：Kathryn L. Rowberg、Grethe Hystad、Matthew L. Clarke、Jazmin Gonzalez与Johnathon M. Taylor合著的《混合化学与颜料：X射线荧光光谱法作为无损技术分析日本彩绘手卷中的颜料》，收录于《在艺术与考古中阐释化学：面向学者的灵感》（*Contextualizing Chemistry in Art & Archaeology: Inspiration for Faculty*），编辑为Kevin Braun与Kristin Labby，美国化学学会（American Chemical Society）2021年出版，页码217-231，DOI：10.1021/bk-2021-1386.ch010。
