 Sourcing the `01_activate_env.bash` is thus _not_ required in this execution mode.
 
+## Quick tests

+We support running coarse experiments with `QUICKTEST=1` to roughly reproduce the behaviour of the `code/` with lower compute requirements.
+
+> Note: this required around 2GB of memory and 1.5h of time on a consumer Notebook with a 12th Gen Intel(R) Core(TM) i7-12800H CPU.

+>
+> - figures/fig_dmd_evals_errors.pdf might not reproduce the eigenvalues
+> - figures/fig_solution_outputs.pdf suffers from the shorter `T=0.5` (as opposed to `T=8`)
+>
+> Also note that running the quick tests will change the existing `output/` and `figures/` and add new files (due to changed filenames).
+> To discard these changes and revert back to the reference state, use:
+>
+> - `git restore output figures`
+> - `git clean -xdf output figures`
