爱因斯坦天文台的成像仪器已经对以小麦哲伦星云（SMC）为中心的超过40平方度的区域进行了测量。勘测大约完成到 10 至 36 尔格/秒的光度，并且检测到的最微弱源（如果在 SMC 中）的光度约为 3 x 10 至 35 尔格/秒。清晰地看到了二十六个源头。其中五个被识别为与 SMC 无关的对象。之前检测到的唯一已知光源是 SMC X-1，当处于高状态时，它是 SMC 中最亮的光源。观察到的第二亮源是先前未知的超新星遗迹（SNR），位于 SMC 的中心部分。其他四个较弱的源可能也是 SMC 中的 SNR。其余 15 个来源尚未确定，并且由于其中一些远离云中心，因此可能并非都是 SMC 成员。
A region of over 40 square degrees centered on the Small Magellanic Cloud (SMC) has been surveyed with the imaging instruments of the Einstein Observatory. The survey is approximately complete to a luminosity of 10 to the 36th ergs/sec, and the faintest source detected, if in the SMC, has a luminosity of approximately 3 x 10 to the 35th ergs/sec. Twenty-six sources were clearly seen. Five are identified with objects not associated with the SMC. The only previously known source detected was SMC X-1 which, when in a high state, is the brightest source in the SMC. The second brightest source observed, a previously unknown supernova remnant (SNR), is located in the central part of the SMC. Four other weaker sources are probably also SNRs in the SMC. The remaining 15 sources are not yet identified and, since some are far from the center of the cloud, are probably not all members of the SMC.
