Agarwal parameter and eigenvalues for the second-order matrix of moments M(2,2) for the generated photon-subtracted TMSVS as a function of the squeezing parameter. The Agarwal parameter in a certifies the nonclassical nature of P-function corresponding to the generated photon-subtracted states for different number of subtracted photons l. The eigenvalues in b demonstrates the possibility of tuning the degree of quantum correlations by controlling the squeezing parameter of the source and the number of subtracted photons. The curves represent our theoretical predictions for l = 0 (blue solid line), l = 1 (red-dashed line), l = 2 (pink dash-dotted line), and l = 3 (black-dotted line)
