Log of Major Tutorial Updates¶
How to find version histories¶
Notebook tutorials¶
All Jupyter Notebook tutorial headers contain the date “last verified to run”. If the date in the file you are using does not match the date shown in that file in the “prod” branch of the tutorial-notebooks repository, your version is out of date. Follow the instructions for what to do if notebooks do not automatically update in the Troubleshooting tips.
A full history for all tutorial notebooks can be accessed in GitHub by going to the tutorial-notebooks repository and clicking on “commits” under the green “code” button. The history of a given tutorial can be accessed by clicking on its filename in the repository and then clicking on “history” (near upper-right).
Portal, command line, and API tutorials¶
All Portal, command line, and API tutorials contain the date last verified to run near the top of their page.
All tutorials for the Portal aspect, for the command line (Notebook Aspect), and for the API aspect are kept in the dp0-2_lsst_io repository.
The full history for any given tutorial can be accessed via GitHub by going to the tutorial of interest (e.g., the beginner Portal tutorial), and clicking on “history” (near upper-right).
Major Updates Log¶
Nov 15 2024¶
Tutorial notebook 13a (Image Cutout SciDemo) was updated to demonstrate how to retrieve cutouts without writing to disk, to add more context about use of IVOA, and to optimize the efficiency of TAP queries.
Nov 1 2024¶
Tutorial notebook 03c (Big deepCoadd Cutout) was updated to include an appendix demonstrating an alternative method of identifying overlapping exposures.
Oct 31 2024¶
The recommended image of the RSP at data.lsst.cloud was bumped to Weekly 2024_42 (but this prompted no major changes to any tutorials).
Oct 24 2024¶
The dp02 alias for the butler repository holding the DP0.2 data set was updated to
provide read access only.
This change accommodates evolution in the butler service and better aligns with the functionality to be expected
for Data Preview 1.
Tutorial notebooks 09a and 09b (custom coadds) were updated to use the dp02-direct butler repo alias, which connects
to the writeable version of the DP0.2 butler repository.
This functionality, and the -direct option, is temporary and should only be used when
write access to the DP0.2 butler is absolutely necessary.

In notebooks 02 and 06b, deprecated Bokeh keyword arguments “plot_height” and “plot_width” were replaced with “height” and “width”. The same two notebooks were updated to cast the objectId to a string, because Bokeh was not able to handle such large integers.
An update that was required in many notebooks was replacing “get_tap_service()” with “get_tap_service(“tap”)” (due to deprecation of the former syntax).
Finally, calls to the deprecated method “butler.getDirect()” were replaced with “butler.get()” in a few places.
May 24 2023¶

Notebook 06a, Section 2.1 has been updated to use calexp.visitInfo.id and calexp.filter.bandLabel.
Many notebooks have had minor updates to use SELECT TOP instead of MAXREC (the latter produces an unavoidable but non-fatal warning)
