54 54  * BAM measurement: difference between electrons and timing system
55 55  ** usually the BAM signal has to be added to the delay ...
56 56  ** it is the best to test addition/subtraction and check the results on a step function (more/less sharp) - if there is no change of the data with + and - there is anyway something wrong. please contact your local contact for more information / help

57 57  * Streak camera: difference between electrons and optical laser
58 58  ** it is a slow signal and should only be used as a rolling average over multiple minutes
59 59  ** if you see a drift in the streak camera which you do not see in the BAM it is resulting from the optical laser
60 60  ** if this (BAM - streak camera signal) is significant e.g. 200 fs over 1 h, it means the drift compensation was probably off and it should be compensated
61 61  ** addition/subtraction is dependent on the setup and have to be checked
