目标。我们利用XMM-Newton反射光栅光谱仪(RGS)对明亮的Seyfert 1星系Mrk 509进行了研究,首次利用XMM-Newton的RGS多指向模式来约束该天体的流出特性。我们从 Mrk 509 的 600 ks 光谱图中获得了非常准确的光谱特性,质量极佳。方法。我们对 RGS 的有效面积进行了准确的相对校准,并得出了准确的绝对波长校准。我们改进了添加时间相关光谱的方法,并将光谱拟合的效率提高了两个数量级。结果。利用 XMM-Newton 的新 RGS 多指向模式时的光谱数据质量,我们表明:
Aims. We study the bright Seyfert 1 galaxy Mrk 509 with the Reflection Grating Spectrometers (RGS) of XMM-Newton ,u sing for the first time the RGS multi-pointing mode of XMM-Newton to constrain the properties of the outflow in this object. We obtain very accurate spectral properties from a 600 ks spectrogram of Mrk 509 with excellent quality. Methods. We derive an accurate relative calibration for the effective area of the RGS and an accurate absolute wavelength calibration. We improve the method for adding time-dependent spectra and enhance the efficiency of the spectral fitting by two orders of magnitude. Results. Taking advantage of the spectral data quality when using the new RGS multi-pointing mode of XMM-Newton, we show that
