+===== September 2025 - fiber tests =====
 Testing with fiber from FTO, two spools, each with 3 legs. Spool1=241587, Spool2=241586. Each spool has 3 legs. Also tested with short 50 micron fiber. Tests going through FPU calibration channel. Did several sequences.  Images are 50s flat (quartz+LED) and 120s ThAr; if sequence has 3 images, the first is a guider image.

-In the first sequence, Spool 2 legs 2 and 3 appear best, with leg 1 a bit worse. Leg 3 on spool 1 is about the same as leg 1 on spool 3, followed by leg 2, with poorest being leg 1 on Spool 1. This roughly matches the expectations from the {{:test:final_report_pf_02_compressed.pdf?linkonly|FTO test report}} (pages 9 and 12).
