✦ Synopsis
In our article "Using electric actuation and detection of oscillations in microcantilevers for pressure measurements", we miscalculated two values, using the frequency f where we should have used the angular frequency ˝= 2 f, After taking into account that f = ˝/2 , the correct value of the damping parameter is 3.21 × 10 -8 N s m -1 under a He environment at room pressure (calculated using Eq. ( )). Similarly the slope of the 1/Q E vs. pressure plot (C 1 ) in the molecular region calculated using Eq. ( ) is 1.43 × 10 -4 Torr -1 after correction. Though the legend of our graphs reads "driving frequency ˝(Hz)", we plotted the data using the driving frequency (f) rather than the angular frequency ˝in rad/s.
