8 %[Description]
9 % This function adds the neccessary RFPDs and DCPDs on
10 % an interferomter model. In the name of this file, '00' means
11 % the TEM00 mode and hence these are the probes dedicated only for
12 % the length sensing and not for angular sensing.
13 % Example usage :
14 % par = paramC1;
15 % opt = optC1(par);
16 % opt = probesC1_00(opt, par);

28 % Here the second return value of the addSink function is used.
29 % This return value is the serial number of the Sink, which is
30 % can be used in place of its name for linking (with a marginal
31 % increase in efficiency).

33 % 3rd addSink argument is power loss, default is 1
34 % Attenuator set to match what is there in the real IFOs, maybe.
