Notebook for SPARCL + Jdaviz

[weaverba137]

This PR adds a how-to for displaying SPARCL spectra in Jdaviz (specifically Specivz). This notebook was initially developed at .Astronomy 12.

Hi @weaverba137 I've gone through and added section descriptions and other small formatting edits. Jdaviz is available on gp02 if you would like to review/test it on there. @rnikutta and @galaxyumi , can yall take a look at this notebook as well?

@weaverba137 and @jacquesalice, here are more comments:

1. The last two commente-out lines in the cell where you define the function on_selected can be deleted if they are no longer in use.
2. The last cell for making plot could have more description in the markdown. For example, featuring a drop down bar where one can select a target to display its spectrum with the best-fit model.
3. The y-axis label is not following the scientific unit style conventions, e.g.,[erg s^{-1} cm^{-2} A^{-1}].
4. The x-axis ticks are too busy to read. Maybe changing to nm? I am getting a long warning box complaining about the Angstrom anyway.
5. It would be great if the plot's legend could be more informative. Currently, they are random(?) two alphabets in red and black colors for model and data.
6. Please take care of this long warning if possible. Otherwise, please leave a comment about the warnings in the markdown not to scare the users.

From the comments above:

1. Fixed.
2. Fixed.
3. Waiting on a fully viable notebook server to test. This may be an internal feature of Jdaviz that cannot be changed.
4. Waiting on a fully viable notebook server to test. This may be an internal feature of Jdaviz that cannot be changed.
5. The alphabetical indexes are an internal feature of Jdaviz. We cannot change that in this notebook.
6. Waiting on a fully viable notebook server to fix.

Updates:

• The warnings are now fixed.
• The y-axis label looks fine to me.
• The x-axis looks fine to me.

@jacquesalice, I think this is ready to go, but it should be tested on gp02 when it becomes available again, and also tested on gp12 when Jdaviz is installed on that system.

PS, I updated the HTML version on the last commit. Please double-check that it looks OK.

I've retested this notebook with the new 'Python 3' kernel on gp02. Please review again. There are no major changes from last time, but it has been a while since we were able to test this.

Hi @weaverba137 , @jacquesalice , @galaxyumi : checking on the status of this notebook. From Ben's last comment it was retested on gp02. What are the next steps after reviewing this version before it can be deployed to prod/gp12?

[weaverba137]

I believe it requires the Python 3.10 kernel to be installed on the production server, so that might also be a question for @mjfitzpatrick.

@jacquesalice, it should be possible to at least review this notebook on gp13 so that it is ready to merge if not yet fully merged.
