chore: remove vestigial pixel_size param (0.187)#288
Merged
Conversation
pixel_size = 0.187 has had no consumer since the cs_util.size migration (bfac233). It is also not the tile scale: 0.187 is the MegaCam center-of-field native scale, not the tile scale used downstream (real tiles: 0.1857; sims: 0.185 — see UNIONS-WL/MultiBand_ImSim#2).

Summary
pixel_size = 0.187has no consumer.git grep -n pixel_sizeondevelopfinds only its two definitions:No other file reads it. Its last consumer was removed in the
cs_util.sizemigration (bfac233).Deleting beats correcting the value. Any future consumer should read the image WCS or the tile pixel scale (0.1857 for real tiles, 0.185 for sims). See UNIONS-WL/MultiBand_ImSim#2. A plausible-looking wrong constant left in place invites reuse.
Closes UNIONS-WL/MultiBand_ImSim#2
Test plan
git grep -n pixel_sizeon develop confirmed no consumer before deleting— Fable, on behalf of Cail
