我们已经用从斯皮策SINS和星暴样本中提取的附近34个星系的韦斯特堡阵列，在18厘米和22厘米处获得了中等深度的射电连续谱成像，以实现免费分析。次样本的光学长轴直径超过5角分，位于赤纬以北12$\fdg$5。次样本星系的形态类型和恒星形成率范围非常广泛。每个星系都有可能进行分辨探测。这构成了第一次在GHz无线电频率下对大约一半的样本进行检测。对样品的总强度和偏振特性的分析将发表在配套论文中。目标星系的离子{H}{I}和OH的主线都在观测的带通范围内，尽管速度分辨率很低。只有两个低质量椭圆星系在离子{H}{I}中未被探测到。其中四个次样本星系在OH主线吸收中被探测到，其中包括两个新的探测。结果以图像图集的形式呈现，其中贯穿始终使用标准传递函数和图像大小，并由此并排显示射电连续体、DSS光学和集成图像。表中列出了所有靶的连续谱和直线光度法。
We have obtained moderately deep radio continuum imaging at 18 and 22 cm with the Westerbork array of 34 nearby galaxies drawn from the Spitzer SINGS and Starburst samples to enable complimentary analysis. The sub-sample have an optical major axis diameter in excess of 5 arcmin and are North of Declination 12$\fdg$5. Sub-sample galaxies span a very wide range of morphological types and star formation rates. Resolved detection was possible for every galaxy. This constitutes a first time detection at GHz radio frequencies for about half of the sample. Analysis of both total intensity and polarization properties of the sample will be published in companion papers. Both the $\ion{H}{i}$ and OH main-lines of the target galaxies were within the observed band-pass, albeit with only coarse velocity resolution. Only two low mass elliptical galaxies were undetected in $\ion{H}{i}$. Four of the sub-sample galaxies were detected in OH main-line absorption, including two new detections. The results are presented in the form of an image atlas for which a standard transfer function and image size are used throughout and whereby the radio continuum, DSS optical and integrated $\ion{H}{i}$ are displayed side-by-side. Continuum and $\ion{H}{i}$ line photometry are tabulated for all targets.
