The synchronization problems were of different kind:
- data for some subscans were not available, i.e. the IMBFits tables are either empty or have wrong time slot of data
- data after the subscan start are first set (i.e. not 0) then 0
- data before the subscan end are 0
- the IMBFits were created 5 to 10 minutes after the observation was finished;
the IMBFits files of 1mm & 2mm were created at the same time, this indicates that the creation of the IMBFits did not take so long but that the NIKA data were first available after such time delay
