The file 2205_01122data.csv contains noise subtracted single qubit tomographical data. The column name indicate the following:

-s-
number of times the free time evolution is applied

-run-
number of repetition of the experiment

-inst-
the input state

-p, q-
define the free and perturbed evolution

-H,V,P,M,R,L-
measurement clicks (noise subtracted) when projecting on the H/V/P/M/R/L polarization state

-H_std,V_std,P_std,M_std,R_std,L_std-
the corresponding standard deviations
