Use the new coll[]/collErr[] interface so sigmaSC-vs-temp-py.txt computes both SigmaSC_10 and SigmaSC_150 in one block instead of one block per collection. Collection 0 is addressed by index (coll[0]) and collection 1 by name (coll['...Tscan.db']) to show both addressing modes. Output is unchanged. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
