"For both of our examples, we will use the same data file. The example of creating static images can be used on any `numpy.ndarray` object and the WCS axes may be optionally included with any `astropy.wcs.WCS` object. The Jdaviz example below is designed to work for Roman, but Jdaviz can also work with other data and file types. For the interested reader, a link to the Jdaviz documentation is provided in the Additional Resources section below.\n",

"A fuller explanation of how to load and work with Roman ASDF files is provided in the notebook tutorial XX, and we assume that the reader has already consulted that tutorial. For now, we will read in the data using the `roman_datamodels` package."
