Spectra provides primary shot timing aboard Langseth. The 'shot' data set includes only the event messages (message #62) The 'tagger' data set includes all output from the TM-4. The TM-4 is used as an event logger to log shot times from digishot. Spectrum Time Tagger Data Spectrum TM-4 time and frequency system data ![]()
