I think we should also be able tell the number of "polarization" hops (1,2 or 3) from the quicklook data and report if the issue effects one or both cameras. So far testing has been offline, with unit tests on another device and a full up integration test with the lens cover in. Tomorrow we should be able to give a real test. ___end___ KCOR COMMENT BY KCOR: Wed May 13 23:20:41 GMT 2026 KCOR file transfer report KCor created 840 .bin files 834 .fts files NOTICE ? 6 .bin file(s) with no matching .fts: 20260513_175059_kcor.bin 20260513_183358_kcor.bin 20260513_202318_kcor.bin 20260513_215418_kcor.bin 20260513_224734_kcor.bin 20260513_230109_kcor.bin Remote site is complete ? no rsync required. ___end___ ** GENERAL PM lisapg ** : Thu May 14 00:28:51 GMT 2026 Jay completed the PSPT dome skirting today.
