Example command-line task that computes simple statistics on an image.
Example command-line task that computes simple statistics on an image.
This task was written as an example for the documents How to Write a Task and How to Write a Command-Line Task. The task reads in a "calexp" (a calibrated science exposure), computes statistics on the image plane, and logs and returns the statistics. In addition, if debugging is enabled, it displays the image in ds9.
The image statistics are computed using a subtask, in order to show how to call subtasks and how to retarget (replace) them with variant subtasks.
The main method is run.
This task supports the following debug variables:
display
To enable debugging, see baseDebug.
