 The multi-hit capability requires some special attention. Let's imagine a situation where the rate from OBJ detector is much higher than from the FP detector. During this window, the MTDC will record one hit from the FP scintillator (E1 up, which SpecTcl uses as the start ToF reference) and multiple hits from the OBJ scintillator (stops). As a results, SpecTcl will generate an array of OBJ-FP ToFs  called **s800.fp.vmetdc.obj.i**, where i=0 stands for the first hit, i=2 second hit and so on (the corresponding array for XFP-FP TOF is **s800.fp.vmetdc.xfp.i**). The multi-hit capability requires some special attention.
