Attributes Documentation

filename

The name of the file the object was written to.

serialized

The serialization model for this object (serialization.ArchiveTree).

Methods Documentation

get(component: str | None = None, storageClass: str | None = None, **kwargs: Any) → Any

Perform a partial read.

Parameters

component

Component to read instead of the main object. This requires the roundtrip to use a butler, raising unittest.SkipTest otherwise; this generally means these tests should be nested within a subTest context.

storageClass

Override storage class name to affect the type returned by the get. Only used if a butler is active.

**kwargs

Keyword arguments either passed directly to fits.read or used as parameters for a get.

Return

object

Result of the partial read.

inspect() → HDUList

Open the FITS file with Astropy.
