Subject: Computing corrected time from binary data...what is t_0,0? 

t0,0 refers to the time of cell #0 of channel #0. So basically you keep channel 0 fixed, calculate the difference of each channel's cell #0 in respect to channel 0, and align all channels except channel 0 so that their cell #0 has the same value. There is an inconsistency between the channel numbering. The formula uses 0...3 and the manual says "channel 1" but it means actually the first channel, which uses index "0".

In the equations for computing the corrected time for channels other than channel 1, does anyone know what the term t0,0 refers to?  This is the last term in the last equation on page 24 of DRS4 Evaluation Board User’s Manual, Board Revision 5 as of January 2014, Last revised: April 27, 2016.

Screenshot from User's Manual is attached below.

Thank you!
