标题： Stellar models in IR calibration

摘要： 对于分析ISO-SWS数据的天文学界来说，当评估和鉴定观测数据时，首先要考虑的是通量校准的准确性。 由于校准过程并不直接，并且错误的校准可能导致结果的高估或低估，因此在处理数据时，了解完整的校准过程以及仍然存在的校准问题至关重要。 检测校准问题的一种方法是将观测数据与校准源整个样本的理论预测进行比较。 通过使用一种迭代过程，其中涉及校准和理论建模的改进，我们将证明已经构建了一个一致的红外光谱理论数据集。 该数据集已被用于推导OLP10的ISO-SWS通量校准。 我们将展示，（高通量）ISO-SWS观测的相对通量校准精度在波段1已达到2%的水平，并且随着引入记忆效应校正以及使用我们的合成光谱进行通量校准推导，波段2的通量校准精度显著提高，在波段2达到了6%的水平。 显示英文摘要

摘要： For the astronomical community analyzing ISO-SWS data, a first point to assess when judging and qualifying the observational data concerns the flux calibration accuracy. Since the calibration process is not straightforward and since a wrong calibration may lead to an over- or underestimation of the results, knowledge on the full calibration process and on the still remaining calibration problems is crucial when processing the data. One way to detect calibration problems is by comparing observed data with theoretical predictions of a whole sample of calibration sources. By using an iterative process in which improvements on both the calibration and the theoretical modelling are involved, we will demonstrate that a consistent theoretical data-set of infrared spectra has been constructed. This data-set has been used to derive the OLP10 flux calibration of the ISO-SWS. We will shown that the relative flux calibration accuracy of (high-flux) ISO-SWS observations has reached a 2% level of accuracy in band 1 and that the flux calibration accuracy in band 2 has improved significantly with the introduction of the memory-effect corrrection and the use of our synthetic spectra for the flux calibration derivation, reaching a 6% level of accuracy in band 2.
