Clock Synchornization

[zoyavallari]

Revisit timestamp calibration to synchronize the various clocks we have in the various readout electronics hardware

• LRO and each PACMAN controller have their own dedicated clocks that tick at slightly different frequencies
• This was carefully calibrated in module0 data, but never revisited for the module1-3 data

In addition to extracting the calibration constraints from mod1-3 data, need to automate the way these are extracted and applied in the processing routines.

From Kevin's talk

• Module0 calibration constants for CRO, e.g., https://github.com/DUNE/ndlar_flow/blob/main/src/proto_nd_flow/reco/charge/timestamp_corrector.py#L42-L44
• How exactly to extract these constants for other modules and other runs from the data stream needs to be re-established and included in an ndlar_flow module explicitly. (application already exists)
• Example: module 1 data
