2-D frame| RESPITE: The CASA Toolkit Page: Documentation: Block Library Index:Option |
Option has two inputs, a compulsory input, in1, and an optional input in2. If the optional input is left unconnected then in1 is passed to the output out1. If in2 is connected then in1 is discarded and in2 is passed to out1 instead.
The block is useful for writing reusable intermediate blocks who's behaviour depends on which inputs are supplied.
