真实BiSON-like日震资料的模拟
The simulation of realistic BiSON-like helioseismic data
摘要：
在模拟全圆盘日震数据时，仪器噪声传统上被视为与时间无关。然而，在现实中，由于视线速度变化和可能的硬件退化，仪器噪声通常会随着时间的推移而在一定程度上变化。在这里，我们提出了一种新的技术，模拟伯明翰太阳振荡网络（BiSON）日震数据与更现实的模拟仪器噪声。这是通过模拟BiSON仪器观测到的钾太阳夫琅和弗线来实现的。然后可以模拟线的红色和蓝色翼中的强度测量，并且可以添加适当的时间依赖性仪器噪声。然后，可以以与真实数据相同的方式形成模拟的时间序列。在这里，我们提出了模拟方法和第一代的BiSON类仪器噪声时间序列。
英文摘要：
When simulating full-disc helioseismic data, instrumental noise has traditionally been treated as time-independent. However, in reality, instrumental noise will often vary to some degree over time due to line of sight velocity variations and possibly degrading hardware. Here we present a new technique for simulating Birmingham Solar Oscillations Network (BiSON) helioseismic data with a more realistic analogue for instrumental noise. This is achieved by simulating the potassium solar Fraunhoffer line as observed by the BiSON instruments. Intensity measurements in the red and blue wing of the line can then be simulated and appropriate time-dependent instrumental noise can be added. The simulated time-series can then be formed in the same way as with real data. Here we present the simulation method and the first generation of a BiSON-like instrumental noise time series.
