dIY(lR, slR, theta, stheta)

Calculate quadrature (out-of-phase, Y) signal component

delta I_Y = delta R * sin(theta)

The lock-in R offset is not substracted, since it is assumed to be in-phase

Parameters:

• lR – R from lock-in

• slR – standard error of R from lock-in

• theta – offset-corrected theta from lock-in

• stheta – standard error of offset-corrected theta from lock-in

Returns:

delta I_Y
