Time zero with BAM definition
Currently the BAM is used only as a jitter correction. In a run we substract the BAM mean value in the analysis. However:
- the BAM has long term oscillation with the Moon tide (12h)
- sometimes, the machine is readjusted an the BAM jumps to a different average value
If we can confirm that the t0 seen in experiment changes also with the absolute BAM values, we should correct timing data by the BAM. This mean t0 is not only defined by the delay stage position, but also by the mean BAM value for that particular reference run. Analysis code will have to change accordingly (both BOZ and scattering).
