Revised driz notebook: optimize image sampling

[rjavila]

This notebook checklist has been made available to us by the Notebooks For All team. Its purpose is to serve as a guide for both the notebook author and the technical reviewer highlighting critical aspects to consider when striving to develop an accessible and effective notebook.

The First Cell

• [x] The title of the notebook in a first-level heading (eg. <h1> or # in markdown).
• [x] A brief description of the notebook.
• [x] A table of contents in an ordered list (1., 2., etc. in Markdown).
• [x] The author(s) and affiliation(s) (if relevant).
• [x] The date first published.
• [x] The date last edited (if relevant).
• [ ] A link to the notebook's source(s) (if relevant).

The Rest of the Cells

• [x] There is only one H1 (# in Markdown) used in the notebook.
• [x] The notebook uses other heading tags in order (meaning it does not skip numbers).

Text

• [x] All link text is descriptive. It tells users where they will be taken if they open the link.
• [ ] All acronyms are defined at least the first time they are used.
• [ ] Field-specific/specialized terms are used when needed, but not excessively.

Code

• [x] Code sections are introduced and explained before they appear in the notebook. This can be fulfilled with a heading in a prior Markdown cell, a sentence preceding it, or a code comment in the code section.
• [x] Code has explanatory comments (if relevant). This is most important for long sections of code.
• [ ] If the author has control over the syntax highlighting theme in the notebook, that theme has enough color contrast to be legible.
• [ ] Code and code explanations focus on one task at a time. Unless comparison is the point of the notebook, only one method for completing the task is described at a time.

Images

• [ ] All images (jpg, png, svgs) have an image description. This could be

  • [ ] Alt text (an alt property)
  • [ ] Empty alt text for decorative images/images meant to be skipped (an alt attribute with no value)
  • [ ] Captions
  • [ ] If no other options will work, the image is decribed in surrounding paragraphs.

• [ ] Any text present in images exists in a text form outside of the image (this can be alt text, captions, or surrounding text.)

Visualizations

• [ ] All visualizations have an image description. Review the previous section, Images, for more information on how to add it.

• [ ] Visualization descriptions include

  • [ ] The type of visualization (like bar chart, scatter plot, etc.)
  • [ ] Title
  • [ ] Axis labels and range
  • [ ] Key or legend
  • [ ] An explanation of the visualization's significance to the notebook (like the trend, an outlier in the data, what the author learned from it, etc.)

• [ ] All visualizations and their parts have enough color contrast (color contrast checker) to be legible. Remember that transparent colors have lower contrast than their opaque versions.

• [ ] All visualizations convey information with more visual cues than color coding. Use text labels, patterns, or icons alongside color to achieve this.

• [ ] All visualizations have an additional way for notebook readers to access the information. Linking to the original data, including a table of the data in the same notebook, or sonifying the plot are all options.

Hello @haticekaratay. Not sure why the CI check is failing during package installation. I tested my NB by creating a clean environment with python==3.11.7 and then pip installed the packages in the requirements.txt file. The NB ran successfully. Any advice would be appreciated.

Closing this pull request as pull request #268 already contains the updates to this notebook, and it will be reviewed together with that.

Hi Hatice, I don't understand why this was closed? This is a different notebook than the one in #268 (using DS9 regions)

What do we need to do to get this notebook running?
