The LscEmul class emulates the workings of the front-end LSC software. The computations are made in stages with the inputs and outputs of each stage corresponding to channels that can be read out. The stages are as follows:

1. Calculation of I and Q phases
   • Inputs: Error photodiode signals
   • Outputs: Combined error signals (AS_I, AS_Q, POB_I, POB_Q, RFL_I, RFL_Q).
   • Processing: The raw error signals are summed over all appropriate photodiode signals giving raw I and Q phase signals. The raw signals are offset by specified constants, optionally dewhitened and rotated by a specified phase to give the true I and Q phases.
2. Calculation of control signals
   • Inputs: Error Signals
   • Outputs: Control signals (MICH, PRC, DARM, CARM)
   • Processing: Linear combinations of the error signal phases are calculated by multiplying a vector of the error signals by the input matrix.
3. • Inputs:
   • Outputs:
   • Processing:
