ABSTRACT
Part of side switch activities.
The operation and positioning of the Channel Select Mechanism (CSM) will be verified for the WFC3 UVIS and IR channels. An extended target
will be observed in both channels to verify that the field of view is not blocked or vignetted in any way when the CSM is set for UVIS and IR
channel operations. Internal IR flat field images will also be used to verify the correct positioning of the IR diffuser paddle.

Comments: Automatic CR-SPLIT mode is not used. Instead two individual, and identical, UVIS exposures are obtained before and after the IR exposures, thus allowing for a check of repeated motion of the CSM in an
d out of the beam.
