Here's the numbers from the latest baseline survey simulation:
(median depths after 10 years, assuming Gaussian errors)

Do you know if the processing was optimized for LSB features or was it the standard pipeline? By eye the depth doesn’t seem that different from your Mihos+2017 paper

Not sure about the processing of this Rubin image, but I know there is a lot of work going on in the project to work out how to optimize things for LSB work. And to be fair, my image is stretched to emphasize LSB light, whereas the Rubin release image is trying show a much wider dynamic range.....

I didn’t mean to trash talk LSST, just that even with this initial processing and without stretching it’s already close to what you had so it’s already pretty good. I look forward to how deep it can be pushed!
