We introduce the Swift/UVOT+MaNGA (SwiM) value-added catalog, which comprises 150 galaxies that have both Sloan Digital Sky Survey (SDSS)/MaNGA integral field spectroscopy and archival Swift/UVOT near-UV (NUV) images. The similar angular resolution between the three Swift/UVOT NUV images and the MaNGA maps allows for a high-resolution comparison of optical and NUV indicators of star formation, crucial for constraining quenching and attenuation in the local universe. The UVOT NUV images, SDSS images, and MaNGA emission line and spectral index maps have all been spatially matched and reprojected to match the point-spread function (PSF) and pixel sampling of the Swift/UVOT uvw2 images and are presented in the same coordinate system for each galaxy. The spectral index maps use the definition first adopted by Burstein et al., which makes it more convenient for users to compute spectral indices when binning the maps. Spatial covariance is properly taken into account in propagating the uncertainties. We also provide a catalog that includes PSF-matched aperture photometry in the SDSS optical and Swift NUV bands. In an earlier companion paper, we used a subset of these galaxies to explore the attenuation laws of kiloparsec-sized star-forming regions. The catalog, maps for each galaxy, and associated data models are publicly available on the SDSS website.

我们介绍 Swift/UVOT+MaNGA (SwiM) 增值目录，其中包含 150 个星系，这些星系同时拥有斯隆数字巡天 (SDSS)/MaNGA 积分场光谱和档案 Swift/UVOT 近紫外 (NUV) 图像。三张 Swift/UVOT NUV 图像和 MaNGA 地图之间的相似角分辨率允许对恒星形成的光学和 NUV 指标进行高分辨率比较，这对于限制局部宇宙中的淬灭和衰减至关重要。UVOT NUV 图像、SDSS 图像和 MaNGA 发射线和光谱索引图都经过空间匹配和重新投影，以匹配 Swift/UVOT uvw2 图像的点扩散函数 (PSF) 和像素采样，并以相同的坐标呈现每个星系的系统。光谱索引图使用 Burstein 等人首先采用的定义，这使得用户在对地图进行分箱时更方便地计算光谱索引。在传播不确定性时适当地考虑了空间协方差。我们还提供了一个目录，其中包括在 SDSS 光学和 Swift NUV 波段中与 PSF 匹配的孔径光度测量。在较早的一篇配套论文中，我们使用这些星系的一个子集来探索千秒差距大小的恒星形成区域的衰减规律。目录、每个星系的地图和相关数据模型可在 SDSS 网站上公开获取。我们使用这些星系的一个子集来探索千秒差距大小的恒星形成区域的衰减规律。目录、每个星系的地图和相关数据模型可在 SDSS 网站上公开获取。我们使用这些星系的一个子集来探索千秒差距大小的恒星形成区域的衰减规律。目录、每个星系的地图和相关数据模型可在 SDSS 网站上公开获取。
