-  * SpecTcl calculates the OBJ-FP and XFP-FP ToFs by substracting the E1 up time (MTDC channel ​15) to the OBJ time (MTDC channel 3) and the XFP time (MTDC channel 2) +  * The S800 SpecTcl ​used for online analysis ​calculates the OBJ-FP and XFP-FP ToFs by substracting the E1 up time (e.g. MTDC channel ​0) to the OBJ time (MTDC channel 3) and the XFP time (MTDC channel 2). (Note that a better way to calculated these ToFs should use the average time E1_up and E1_down.)
   * Note that the same flat ribbon cable connected to the MTDC is also feeding the scaler module. Thus, the 16 channels in the MTDC are exactly the same as channels 16-31 of the scaler module   * Note that the same flat ribbon cable connected to the MTDC is also feeding the scaler module.
