Detailed Description

Class providing native access to MIRIAD images.

Intended use:

Public interface

Review Status

Test programs:: tMIRIADImage

Prerequisite

Etymology

This class provides native access to MIRIAD images.

Synopsis

A MIRIADImage provides native access to MIRIAD images by accessing them with the TiledFileAccess class. – or – the native miriad I/O routines. The MIRIADImage is read only. – really – ??

Example

MIRIADImage im("cube1"); 
LogIO logger(or);
ImageStatistics<Float> stats(im, logger);
Bool ok = stats.display();                              // Display statistics

Motivation

This provides native access to MIRIAD images.
