Recently we started to have problems with the beamspot alarm at the beginning of fills when LHC does an emittance scan. Detailed analysis of such a situation can be found at
https://twiki.cern.ch/twiki/bin/viewauth/CMS/OnlineBeamSpot#23_Aug_2017_audio_alarm_in_run_3

The problem is that the beamspot moves a lot in z direction during this 10 LS-long operation (4 mins), and it is difficult to reconstruct tracks with the present cylinder of origin setting (optimized for stable beams and normal conditions).

It seems that there is no software-signal which could tell us that LHC does an emittance scan.

Since this issue persists, the only way is to increase the "limit of the number of consecutive LSs without beamspot" from 10 to 15. This disables the false alarms (an emittance scan usually lasts for just about 10 LSs, 4 minutes).

Comparison is ready
https://cmssdt.cern.ch/SDT/jenkins-artifacts/pull-request-integration/PR-20325/22608/summary.html

There are some workflows for which there are errors in the baseline:
1306.0 step 4
136.788 step 3
The results for the comparisons for these workflows could be incomplete
This means most likely that the IB is having errors in the relvals.The error does NOT come from this pull request

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar (and backports should be raised in the release meeting by the corresponding L2)
