docs: floor MGE Gaussians at a tenth of the pixel scale - #61
Merged
Conversation
Phase 2 of the sweep started in autolens_workspace#467. Tutorial 5's three hand-rolled MGE ladders now start at `np.log10(dataset.pixel_scales[0] / 10.0)` instead of a hardcoded -2. All three are image-plane galaxy light — HowToGalaxy has no lensing and so no source plane, making the source exclusion that applies in HowToLens inapplicable here.

chapter_2_modeling/tutorial_5_linear_profiles.pybuilds three MGE sigma ladders by hand, all previously hardcoded to-2. They now start atnp.log10(dataset.pixel_scales[0] / 10.0), so the basis stops spending Gaussians ~2 dex below what the data resolves.All three are image-plane galaxy light. The companion HowToLens PR moves one of its ladders to
-4instead, because a lensed source is sampled far more finely than the image pixel scale — HowToGalaxy has no lensing and so no source plane, making that exclusion inapplicable here.Scripts Changed
