We ask for 20 ks of XMM-Newton observation of the High Mass X-ray Binary candidate 1H 1255-567 comma the first pointed observation of this source with a modern imaging X-ray instrument. The aim of the observation is to confirm or refute the X-ray binary nature of the system comma and to test the hypothesis that this source might instead be a gamma Cas analogue.我们申请对大质量X射线双星（High Mass X-ray Binary）候选体1H 1255-567开展时长20千秒的XMM-牛顿（XMM-Newton）望远镜观测，这是该源首次借助现代成像X射线仪器完成的指向观测。本次观测的目标为验证或证伪该系统的X射线双星性质，并检验其可能为仙后座γ型类似源的假说。
