Batch Settings
在处理天文图像时，MEF（Multi-Extension FITS）和FITS（Flexible Image Transport System）是两种常见且功能强大的文件格式。MEF作为FITS的扩展，能在一个文件中容纳多组数据，例如原始图像、校准数据或不同波段的观测结果，这对于复杂的科学研究尤其方便。而FITS则是天文学界公认的标准，其数据结构严谨，元数据丰富，确保了图像信息的完整性和可追溯性。将MEF转换为FITS，通常是为了提取特定扩展中的数据，或是为了兼容只支持标准FITS格式的分析软件或发布平台。无论是科研人员进行数据归档，还是天文爱好者分享观测成果，理解并掌握这两种格式的转换都非常实用，能有效提升工作效率和数据共享的便利性。
