在银河系中心方向上的一些红外天文台的来源，并怀疑是最近或目前的星星形成的地区，已经调查了直接近红外成像和有限的光谱，进一步试图澄清其性质。IRAS源的近红外对应物是根据它们的近红外颜色、与3.5 μm玻璃源的一致性以及一般外观从图像中的各种物体中选择的。测光是从图像中得出的，并与光谱学和以前发表的结果相结合，以确定这些来源是否确实接近银河系中心，以及它们是否年轻
A number of IRAS sources in the direction of the Galactic Centre and suspected of being regions of recent or current star formation have been investigated by means of direct near-infrared imaging and limited spectroscopy in a further attempt to clarify their nature. Near-infrared counterparts to the IRAS sources are selected from the various objects in the images on the basis of their near-infrared colours, coincidence with the 3.5-μm sources of Glass, and general appearance. Photometry is derived from the images, and combined with the spectroscopy and with previously published results to determine whether indeed these sources are close to the Galactic Centre and whether they are young
