ENR CTIO 1.5-m 2022-12-08

Problems: 

At the beginning of the night the GUI showed the following message:

2022-12-08T16:43:18 : SLICER STATUS ERROR

I restarted the GUI and the problem seemed to be solved, BUT...

Along the night (after midnight) I got the same message a couple of times, it happened when observing in the fiber mode. In this mode it took more time than expected for the setup, and the DECKPOS (mm) showed different values, e.g.: 0.8114, 0.549, 0.5188, 0.5626, 0.6767, 0.6553, 0.621804. In this mode the expected value is 2.1495.

When I put manually the fiber mode a red window appears with the SLICER ERROR message. The same windows appeared when I left running the calibrations at the end of the night. I checked the values for DECKPOS in the slicer mode, the value is 0.3894. In this mode the expected value is 0.3905.

I checked the values for the DECKPOS parameter for many previous nights, the values are ok, so the problem seems to be only for tonight.

If the slicer device is failing the data could not be useful… Please check this problem ASAP!

Comments: 

No data from the DIMM monitor the third quarter of the night, as a reference I used the data from the Blanco night report.

No time for RKS0901-4148.
