mwalib

mwalib是一个用于将原始可见性、电压和元数据读取到通用结构的MWA库。mwalib支持现有的“遗产”MWA相关器，以及“MWAX”相关器观测。该库致力于提供单个接口以处理MWA元数据、相关器和电压格式的所有变体，并抽象化读取MWA数据的繁琐细节。唯一例外的是尚未重新组合（重新排列为每个粗通道文件）的原始遗产VCS数据，目前不支持。

mwalib是您可以在以下环境中使用的库

Rust（请参阅examples/*.rs）
C（请参阅examples/*.c）
Python（请参阅examples/*.py）

安装和使用

有关安装说明、概念和使用信息，请参阅MWATelescope Wiki上的mwalib文章。
