Module AIPSData

source code

This module provides the AIPSImage and AIPSUVData classes. These classes implement most of the data oriented verb-like functionality from classic AIPS.

Images can be manipulated by creating instances of the AIPSImage class:

>>> image = AIPSImage('NONAME', 'IMAGE', 1, 1)

For UV data, the AIPSUVData class should be used:

>>> uvdata = AIPSUVData('NONAME', 'UVDATA', 1, 1)

Checking whether the image or UV data actually exists is easy:

>>> image.exists()
False
>>> uvdata.exists()
False

>>> print uvdata
AIPSUVData('NONAME', 'UVDATA', 1, 1)

Checking whether two instance refer to the same data is fairly simple:

>>> image == uvdata
False

>>> image == AIPSImage('NONAME', 'IMAGE', 1, 1)
True

Both classes implement the copy method:

>>> uvjunk = uvdata.copy()
>>> uvjunk == uvdata
True
>>> uvjunk.name = 'GARBAGE'
>>> uvjunk != uvdata
True
