After noticing a "double-spot" on one if the ITMY HWS points on May 26th, Dan suggested turning off the HWS SLED to understand where this scattered light is from. seems to have been there since 08 April ~19:30UTC.

Tonight I turned off the ITMY SLED 7:46 to 8:02UTC and 10:54 to 11:01UTC and the ITMX SLED 10:50 to 10:57UTC. After ALS has been shuttered and with both HWS SLEDs off.

• Scatter pionts on ITMX: (261, 597) , (261, 540)
• Scatter pionts on ITMY: (483, 355 <- WORSE ONE), (467, 380), (450, 354)
  • You can also see a little ITMX SLED leakage on ITMY camera (image with IX SLED on, IY off) but not the revserse.
• Scatter pionts seen on Tuesday 2023/05/09 17:30UTC when PSL input power was 0W, image, but scatter point in a slightly different location. So it isn't PSL light either...

Unsure what this light is. We could try turning down the HWS camera exposure to minimize some of it.
