Slew models a constant slew, i.e. a continuously changing look angle, of an optical system. Slew has the same effect, and is governed by the same sign conventions, as a uniformly changing tilt. Slew takes four parameters, used to specify the initial look angle and its rate of change in x and y. A positive look angle corresponds to the platform side pointing towards +x or +y, and a positive slew rate corresponds to turning in that direction.
Slew has two WaveTrain inputs and two WaveTrain outputs, used to process incoming and outgoing light.

Parameters
xtiltDot	float	X component of slew rate (rad/s)	0.0
ytiltDot	float	Y component of slew rate (rad/s)	0.0
xtilt0	float	Initial x tilt angle (rad)	0.0
ytilt0	float	Initial y tilt angle (rad)	0.0
Inputs
incomingIncident	WaveTrain	describes all light incident from the "incoming" direction	WaveTrain()
outgoingIncident	WaveTrain	describes all light incident from the "outgoing" direction	WaveTrain()
Outputs
incomingTransmitted	WaveTrain	describes all light transmitted in the "incoming" direction
outgoingTransmitted	WaveTrain	describes all light transmitted in the "outgoing" direction
