A 0.0010 arcsec amplitude perturbation would be found in the these data at a 1% false positive level with a 5% miss rate. Assuming MBarn = 0.12 M(solar) yields

We confirm and somewhat extend the limits obtained by Gatewood (1995, Ap&SS, 223, 91). Having removed power at ~ 0.006 day^-1, we have no detection capability at that frequency. Note that even though Barnard's Star is more distant and observed fewer times, we obtain detection limits similar to those for Proxima Cen.
