WebIt stands for Flexible Image Transport System, and for all intents and purposes, it acts as a container (much like a zip file). Within it, one can store several kinds of information: images (2d arrays of values), as the name implies, headers (dictionary like objects with metadata), and sometimes tabular data as well. WebThe IRAF implot task (in the plot package) allows you to examine an image interactively by plotting data along a given line ( x axis) or column ( y axis). When you run the task, a large …
