| + | |||
| + | Up to eight of these words can be present (depending on wheter **time** is greater than 0): six from the Phillips TDC, and two from the XFP-FP and OBJ-FP TACs. The channel number Ch is given by: | ||
| + | |||
| + | ^ Ch ^ Source | ||
| + | | 6 | Phillips TDC time from the A1900 IM2 north scintillator (optional) | ||
| + | | 7 | Phillips TDC time from the A1900 IM2 south scintillator (optional) | ||
| + | | 12 | Phillips TDC time from the RF | | ||
| + | | 13 | Phillips TDC time from the OBJ scintillator | ||
| + | | 14 | Phillips TDC time from the XFP scintillator | ||
| + | | 15 | Phillips TDC time from the LaBr (optional) | ||
| + | | 4 | XFP-FP time-of-flight from TAC | | ||
| + | | 5 | OBJ-FP time-of-flight from TAC | | ||
| + | |||
| + | |||
| + | Note that the time values from the Phillips TDC are subtracted by SpecTcl to the time from the S800 trigger E1 up (encoded in the [[#trigger packet|trigger packet]]) in order to calculate the corresponding time-of-flight. On the other hand, the times from the TACs (Ch 4 and 5) correspond to actual time-of-flight values. | ||
