Loading and Processing MIRIAD Data

miriad-python deals with MIRIAD data on two levels:

• There is a lightweight high-level class, miriad.Data, that allows you to easily store references to datasets, check whether they exist, rename them, and so on.
• There is a lower-level module, mirtask, that lets you open up datasets and access at their contents directly. Doing so successfully requires a familiarity with the details of the MIRIAD data formats, which this documentation does not attempt to provide.

If you’re just getting started with miriad-python, it’s important to understand the high-level miriad.Data class but not necessary to read about the low-level mirtask module just yet.
