通过对CRAB的扫描观测，对硬X射线调制望远镜准直器的点扩展函数进行了在轨定标。我们构造了对理论计算的几何PSFs的经验调整。这种调整包括两部分：一个是用来调整准直器方向偏差的旋转矩阵，另一个是用来校正真实PSFs不均匀性的抛物面函数。在定标观测过程中，通过对扫描速度较低、扫描间隔较小的扫描数据进行拟合，确定调整矩阵和抛物面函数的参数。经点阵源定标后，银面扫描测量的震源定位系统误差为0∘。010，0∘。015，0∘。低能望远镜(LE)、中能望远镜(ME)和高能望远镜(HE)源通量估算的系统误差分别为1.8%、1.6%和2.7%。
We make the in-orbit calibration to the point-spread functions (PSFs) of the collimators of the Hard X-ray Modulation Telescope with the scanning observation of the Crab. We construct the empirical adjustments to the theoretically calculated geometrical PSFs. The adjustments contain two parts: a rotating matrix to adjust the directional deviation of the collimators and a paraboloidal function to correct the inhomogeneity of the real PSFs. The parameters of the adjusting matrices and paraboloidal functions are determined by fitting the scanning data with lower scanning speed and smaller intervals during the calibration observations. After the PSF calibration, the systematic errors in source localization in the Galactic plane scanning survey are 0∘. 010, 0∘. 015, 0∘. 113 for the Low-Energy Telescope (LE), the Medium-Energy telescope (ME) and the High-Energy telescope (HE), respectively; meanwhile, the systematic errors in source flux estimation are 1.8%, 1.6%, 2.7% for LE, ME and HE, respectively.
