 Enclosure box installed 11/18-29. Required taking ferrule out to run through box, so location of traces, etc. changed. Installed 4 temperature sensors inside the box. Cleaned up room and put spare parts on shelf and in drawers.  Installed pass-thrus for cables on FPUs. Connected big dome fan to outlet #10.

+Spectrograph refocussed. Images look more circular in middle of chip at lower focus values, but extracted images show more variation in resolution at the lower values.
+Images from 433000 (left) to 438000 (right) in steps of 1000 near center of chip:
+{{:test:specfoc_433000_438000.png?direct&400}}
+Extracted FWHM/Resolution from the same sequence:
