我们给出了在Groth-Westphal带状场上XMM-牛顿观测的第一个结果。计划暴露时间为70[kS]。我们首先分析了大约50个经过校准和清理的EPIC-PN数据，这些数据是我们可以使用适用于这些观测的早期版本的SAS软件成功处理的唯一数据。在PN视场(FOV)的中心10角处共探测到约110个源。与哈勃太空望远镜(HST)中深探测(MDS)数据库的相互关联显示了X射线源宿主星系的一系列形态特征。在我们的数据中，硬X射线源的光谱确实显示出在z~1处N_H~10^{22}-10^{23}[cm^{-2}]的吸收。
We present the first results of the XMM-Newton observation on the Groth-Westphal Strip Field. The scheduled exposure time was 70 [ks]. We first analyzed about 50 [ks] of calibrated and cleaned EPIC-PN data, which were the only ones we could successfully process with an early version of the SAS software applicable to these observations. A total of about 110 sources have been detected in the central 10 arcmin of the PN field of view (FOV). A cross-correlation with the Hubble Space Telescope (HST) Medium Deep Survey (MDS) database shows a range of morphological properties of host galaxies of the X-ray source. Spectra of hard X-ray sources in our data indeed show absorption in the range N_H~10^{22}-10^{23} [cm^{-2}] at z~1.
