Print this reportOnline monitoring of finesse and losses asymmetryWe implemented an online version (in AlpGc) of the algorithm used in the noise budget to compute the finesse and losses asymmetries.
There are two new channels:
Alp_Gc_DF = finesse asymmetry deltaF / F
Alp_Gc_DP = losses asymmetry in ppm
These values are computed with a short time window. An averaged version is available in the channels Alp_Gc_DF_AVER and Alp_Gc_DP_AVER.
The attached plots compare the outcome of the online monitor with the values computed by the noise budget in the same period. There is good agreement.
