论文摘要
我们介绍了Swift/Uvot+漫画（游泳）增值目录，其中包括150个星系，这些星系具有SDSS/漫画积分田间光谱和档案Swift/Uvot近距离图像（NUV）图像。三个Swift/UVOT NUV图像与漫画图之间的类似角度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，这对于限制当地宇宙中的淬火和衰减至关重要。 UVOT NUV图像，SDSS图像，漫画发射线和光谱指数图均已在空间上进行匹配并重新投影，以匹配Swift/UVOT UVW2图像的点扩散函数和像素采样，并在同一坐标系统中显示了每个星系的同一坐标系统。光谱指数图使用Burstein等人首先采用的定义。 （1984），这使用户更方便地汇总地图时要计算光谱索引。在传播不确定性时，正确考虑了空间协方差。我们还提供了一个目录，其中包括SDSS光学和Swift NUV频段中的PSF匹配的光圈光度法。在较早的同伴论文（Molina等，2020）中，我们使用了这些星系的一部分来探索Kiloparsec大小的恒星形成区域的衰减定律。目录，每个星系的地图以及相关的数据模型在SDSS网站（https://data.sdss.org/sas/dr16/dr16/manga/manga/swim/swim/v3.1/）上公开发布。
We introduce the Swift/UVOT+MaNGA (SwiM) value added catalog, which comprises 150 galaxies that have both 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 re-projected to match the point spread function 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. (1984), 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 (Molina et al. 2020) 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 the associated data models, are publicly released on the SDSS website (https://data.sdss.org/sas/dr16/manga/swim/v3.1/).
