update_parameters()

lsst.ip.isr.deferredCharge.FloatingOutputAmplifier.update_parameters	(		self,
			scale,
			decay_time )

Update parameter values, if within acceptable values.

Parameters
----------
scale : `float`
    Drift scale for the amplifier.
decay_time : `float`
    Decay time for the bias drift.

Raises
------
ValueError
    Raised if the input parameters are out of range.
