8. ally PSD pulse shapes are gathered in a special scientific mode called the Cal bration mode In this mode a maximum curve transmission rate of 40 curves second may be achieved However PSD pulse shapes are also downlinked in Operational and Diagnostics mode Typically one pulse shape is received each 4 seconds in Operational mode while the pulse shape rate in Diagnostics mode depends on the configuration it may also reach 40 curves second PSD pulse shapes from all these modes may be used for template library building PSD library templates may be built from single detector curves these are curves that correspond to events that triggered only a single channel of the AFEE energy chain or from multiple detector curves these are curves that correspond to events that triggered multiple channels of the AFEE energy chain Normally multiple detector events are recognised by the PSD sub assembly and are rejected hence there should be not multiple detector curves However the fact that the AFEE generally has a lower trigger threshold than the PSD can lead to the situation that multiple detector events are detected by AFEE but not the PSD In this case all partners except of one must have an energy below the PSD energy threshold what counts here is the FET energy threshold since it is this threshold that is used for multiple event rejection Multiple detector curves are not correlated by the DPE yet all information is available in the telemetry to p
