摘要：

我们提出了新的数据与SpIOMM，成像傅里叶变换光谱仪连接到1.6米望远镜的天文台杜蒙梅甘蒂奇在魁北克省。最近在技术和数据简化方面的改进大大提高了SpIOMM观测较暗物体或较弱星云谱线以及连续谱源和吸收谱线的能力，并提高了其在近紫外区的调制效率。为了说明这些改进，我们提供的数据超新星遗迹Cas A，行星状星云M27和M97，沃尔夫-拉叶环星云M1-67，螺旋星系M63和NGC 3344，以及相互作用的星系对Arp 84。

英文摘要：

We present new data obtained with SpIOMM, the imaging Fourier transform spectrometer attached to the 1.6-m telescope of the Observatoire du Mont-Mégantic in Québec. Recent technical and data reduction improvements have significantly increased SpIOMM's capabilities to observe fainter objects or weaker nebular lines, as well as continuum sources and absorption lines, and to increase its modulation efficiency in the near ultraviolet. To illustrate these improvements, we present data on the supernova remnant Cas A, planetary nebulae M27 and M97, the Wolf-Rayet ring nebula M1-67, spiral galaxies M63 and NGC 3344, as well as the interacting pair of galaxies Arp 84.
