Step 4: Add two channels and make a strain frame file

  • For the initialization and running the pipeline, please refer step1

  • Access frame cache file by specifying frame_cache and instrument as in step2

  • Define a frame multiplexer(mux) to write channels into a frame as in step3

  • Add CH1(MICH_DELTA_TM) and CH2(MICH_RESIDUAL) and output into ADD divided by the arm length to convert into the strain 

   1 arm_length  = 3000
   2 
   3 ch1 = pp.mktee(pipeline, pipe_dict["CH1"])
   4 ch2 = pp.mktee(pipeline, pipe_dict["CH2"])
   5 add = cp.mkadder(pipeline, cp.list_srcs(pipeline, [ch1, short_queue],\
   6                                                   [ch2,  long_queue]))
   7 add = pp.mkaudioamplify(pipeline, add, 1./arm_length)  # Divide by arm length   
   8 
   9 keys.append("ADD")
  10 pipe_dict["CH1"] = ch1
  11 pipe_dict["CH2"] = ch2
  12 pipe_dict["ADD"] = add
  • Try the tutorial script Compare between ADD and CH3 ()
