With Shingo Fujii

We performed a calibration process for YPcal.

quick result

Alpha values are voltage ratio between ISs in XPcal and GSK(new name of this integration sphere is WSK).  [Main-value Uncertainty-value]

alpha_RxPDpGSK = [0.80513707 0.0008152 ]
alpha_TxPD1pGSK =  [4.50914710e+00 9.30131312e-04]
alpha_TxPD2pGSK =  [1.60451441e+00 9.68060082e-04]

e values are optical efficiency values. [Main-value Uncertainty-value]

e_1 =  [9.69337449e-01 2.60179127e-04]
e_2 =  [1.00473157 0.00164785] (Incidence angle dependent effects not yet included)
