N2 - We present a vectorized version of the MatLab (MathWorks Inc) package tweezercalib for calibration of optical tweezers with precision. The calibration is based on the power spectrum of the Brownian motion of a dielectric bead trapped in the tweezers. Precision is achieved by accounting for a number of factors that affect this power spectrum, as described in vs. 1 of the package. The graphical user interface allows the user to include of leave out each of these factors. Several "health tests" are applied to the experimental data during calibration and test results are displayed graphically. Thus, the user can easily see whether the data comply with the theory used for their interpretation. Final calibration results are given with statistical errors and covariance matrix
