Draft: Bugfix for BdsToKSKS Downstream lines
This fixes a bug introduced in the May deadline MR (!3471 (merged)) for LLDD and DDDD BdsToKSKS lines.
B mesons invariant mass thresholds (4900 MeV < m < 5700 MeV) have been incorrectly applied to Downstream Ks. This results in a (almost) complete candidates rejection for (LLDD) DDDD lines.
This has been spotted looking at the monitoring plots provided by RTA for pre-TS runs where UT was included in datataking. Invariant mass plots for LLLL, LLDD, DDDD lines are attached.
BW estimate of three lines together is 16 MB/s.
Rate estimate is:
- LLLL 90 Hz
- LLDD 70 Hz
- DDDD 70 Hz
