根据年轻恒星在相空间中的分布确定其年龄。

We announce the C23.01 update of Cloudy. This corrects a simple coding error, present since 1990, in one routine that required a conversion from the line-center to the mean normalization of the Lyα optical depth. This affects the destruction of H I Lyα by background opacities. Its largest effect is upon the Lyα intensity in high-ionization dusty clouds, where the predicted intensity is now up to three times stronger. Other properties that depend on Lyα destruction, such as grain infrared emission, change in response.
