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 data
- data after the start of a scan 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;
as the IMBFits files of 1mm & 2mm were created ate the same time it shows that this was not a problem of the IMBFits creation but of the availability of the NIKA data
