Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
evfile	yes	string		Name of existing event file
a specifier which must point to a table of events in a data set.
timebinwidth	no	real	10.0	Time bin width
the width of time bins to use when calculating the correction factors. It is in units of seconds.
pimin	no	int	100	Minimum PI channel to use
the minimum PI channel to use from the data when calculating the count rate. This may be changed to avoid low-energy noise.
pimax	no	int	12000	Maximum PI channel to use
the maximum PI channel to use from the data when calculating the count rate. This may be changed to avoid high-energy noise.
withrandomisation	no	boolean	true	Whether to use randomisation
Because of the quantised nature of the PI channels it is possible when multiplying by a constant to get an output PI channel which is not filled by any of the input channels. To avoid this the PI channels are internally set to be +/- 0.5 of their initial value before applying the constant. Set withrandomisation to false to avoid this behaviour.
