Just so we have a concise table that we can refer to:

  North South Note
Length 1.45(1)" = 3.68(3) cm  
FSR 4070(28) MHz c/2L
Mirror ROCs 1.000(3) m Uncertainty is a guess
g factor 0.9632(3) 1 − L/R
TMS 353(3) MHz νFSR×arccos(g)/π
Transmission loss 297(6) ppm 317(3) ppm ctn:1468
Scatter loss 30 ppm 30 ppm Crude guess
Absorption loss 30(30) ppm 30(30) ppm Extremely crude guess
Finesse 16700(1400) 15100(340), 14600(1000) 2π/(losses); ctn:1480
Cavity pole
116(10) kHz 135(3) kHz, 139(10) kHz νFSR/(2F)
