LiH empty prioritisation

I list below the prioritisation of different settings; I would need to coordinate with Colin to decide how many settings to take - some may drop off the end, depending on the available time. I note that some of the cooling channel tags got tagged differently in the CDB - I will update with the correct CDB tag ASAP.

Solenoid mode

For solenoid mode, the prioritization is - we take our best setting, which is at 140 MeV/c; then we try for a different optics at 140 MeV/c (next best setting); then we try to move off momentum; then we try a couple of different 140 MeV/c optics. I would take all the solenoid mode data in one blob, to avoid the moderately risky "polarity change" operation and to increase the amount of time for data taking.

2017-02-6 M2D on 2T in SSD 140 MeV/c it is our best setting
2016/04 1.2 M2D off 3T in SSD 140 MeV/c it is our next best setting, with a bit different optics
2016/04 2.3 M2D off 3T in SSD 200 MeV/c moving off momentum
2016/04 2.4 M2D off 3T in SSD 240 MeV/c moving further off momentum
2016/04 1.3 M2D off 3T in SSD 140 MeV/c less focussing
2016/04 1.5 M2D off 3T in SSD 140 MeV/c more focussing

Flip mode

2017-02-7 M2D on 2T in SSD 140 MeV/c it is our best setting
2017-02-8 M2D on 3T in SSD 170 MeV/c move off momentum
2016-05-1 M2D off 3T in SSD 140 MeV/c next best LiH setting
2016-05-2 M2D off 3T in SSD 140 MeV/c next best LiH setting
