AsicToFiberMapping: Mirror BP's DCB indices need to be updated #86

Closed ZishuoYang closed 4 years ago

ZishuoYang commented 4 years ago

We see outdated DCB indices on Mirror BPs, while True BPs seem consistent. For example, on Magnet-Bottom-C, the DCB indices corresponding to pigtail X-0-M are shown to be 0/1/3, while we know the swapped indices on the BP schematics are 0/1/2.

As discussed earlier, please take a look at https://github.com/umd-lhcb/pyUTM/blob/master/pyUTM/common.py, more specifically, check if jd_swapping_mirror is correct.

If that is correct, let's see if we can solve the problem either in-person or via vidyo after Tuesday.

I think that the keys and values in jd_swapping_mirror are reversed. I will updated it and test run the mapping script.

I have spot checked for consistency between updated AsicToFiberMapping in tag 0.15 and the Mirror BP schematics, on JP1,2,3,4,6,8,9. The new DCB indices are consistent.
