file Allan analysis.xlsx: Allan-Werle deviation analysis of the measured ring down times. From these data a minimum detectable absorption coefficient of 6.5x10^-12 cm^-1 can be inferred, being the ring-down time under vacuum conditions about 127.5 us.
file Water mole fraction VS time.xlsx : Time development of the CRDS measured water mole fraction with a N_2 flow rate of 2 l/min. The gas pressure was set to the constant value of 2666 Pa. Each data point was retrieved from the recording of a full absorption spectrum of the H_2O 3_(2,2)→2_(2,1) transition, belonging to nu_1 + nu_3 vibrational band.
