AI 中文摘要
本文提出一种简单有效的生成盘平均行星光谱的方法。该技术对从行星中心偏移的不规则网格上生成的分量光谱进行加权平均，考虑了中心到边缘亮度变化及边缘外发射，对像土卫六这样有扩展大气层的天体很重要。方法假设球对称发射，需要足够精细的分量光谱网格来忠实捕捉径向辐射变化，并以土卫六7.7μm甲烷发射为例进行了演示。
英文摘要
Here I present a simple and efficient method for generating a disk-averaged planetary spectrum. The technique uses a weighted average of component spectra generated on an irregular grid of offsets from the planet center. This accounts for variations in center to limb brightness and emission from beyond the limb, which is important for bodies with extended atmospheres such as Saturn's moon Titan. The method assumes spherically symmetric emission and requires a grid of component spectra fine enough to faithfully capture radial radiance variations. An example application to Titan's 7.7 $μ$m methane emission demonstrates the method.
