images.tv

The tv package contains interactive image display utilities.

Notes

For questions or comments please see our github page. We encourage and appreciate user feedback.

Most of these notebooks rely on basic knowledge of the Astropy FITS I/O module. If you are unfamiliar with this module please see the Astropy FITS I/O user documentation before using this documentation.

Many of the images.tv functionality has been replaced by the Python imexam package, which works in conjunction with both the ginga and ds9 viewers. In this notebook we will simply provide the task name for imexam that covers the IRAF task. We leave it to the user to reference the imexam documentation for further information.
