Summary: Delegate Assembly, Friday October 8

We were very fortunate to have Dr. Keith Bechtol, one of the Rubin Commissioning Team members and a faculty at the University of Wisconsin/Madison to be the presenter at the most recent DP0.1 Delegate Assembly. This virtual gathering took place on Friday October 8. Dr. Bechtol showcased various tools which can be used for data visualization, and in particular, Datashader, HoloViews, and Bokeh. The presentation also highlighted the different approaches / philosophies which went into the design of those visualization tools. He first illustrated those tools via two notebooks available to all delegates - those are 08a_Interactive_Image_Visualization.ipynb and 08b_Interactive_Catalog_Visualization.ipynb - both available here.

Dr. Bechtol also presented one more notebook, 08c_Interactive_Image-Catalog_Visualization.ipynb which
highlights interaction between image and catalog displays. This notebook is located in another repository, set up for notebooks contributed by DP0 delegates, located here

The recording of this Assembly can be found at this link.

During a brief break several delegates showed their “profiles,” or one-slide summaries of their research interests. The Assembly continued for the second hour in zoom breakout rooms.

The next DP0 Delegate Assembly will be on Friday October 22, and will cover the details of the Rubin Observatory image processing. The presenter will be Dr. Andrew Bradshaw (member of the Rubin Camera
Subsystem team). We also hope to continue with presentations of the delegate profiles.

What is the procedure for uploading the notebook 08c_Interactive_Image-Catalog_Visualization.ipynb among the other tutorial notebooks accessible in my directory tutorial-notebooks in the RSP? Thanks in advance.

Cheers, Filippo

Hi @dammando,

Notebook 08c by Keith Bechtol has been added to the delegate-contributions-dp01 repository of the rubin-dp0 GitHub organization, where it can be found in the image_catalog_interactivity/ directory (link).

The recommended procedure to obtain this notebook (or any others in that repository) is to git clone the full existing repository delegate-contributions-dp01 (link) into your RSP home directory. These Git instructions (link) should help you out. I put a more detailed step-by-step below as well.

How to Git clone a repository. (Recommended procedure.)
  1. If you haven’t already, first configure git in your RSP account using the git config examples provided here.

  2. Use a terminal in the Notebook Aspect of the RSP to navigate to the directory where you want to put the delegate-contributions-dp01 repository. Find instructions on how to use a terminal in the Notebook Aspect here.

  3. In your web browser, navigate to Click on the green Code button and copy the URL in the box.

  1. In your RSP terminal, type this in the terminal command line: git clone

  2. Left-click on the “raw” button and choose “Save Link As” to save the ipynb code to your computer.

  1. In the Notebook Aspect of the RSP, navigate to the location in your filesystem where you want to put the ipynb file (I keep things in a directory called my_notebooks/), and use the upload button (the up-arrow icon) to upload the ipynb file.
