> Detailed Description :
> We have not been able to run OCAM_monitoring on the
> polar field frames. We get the error messages below. I also
> identify the routine that is crashing and the value of a key
> variable, that because it does not have any element
> above 0 it returns an empty list. We should probably
> contact Konrad Kuijken. I am assigning this to me for the
> moment.
>
> PS I saw this happening in my last shift and I have the
> suspicion that is due to the low FLI.

> indeed one month after the first occurence we got today the next failure of OCAM_monitoring. So it is clearly lunar phase related.
