Notes. ⁽¹⁾ Helio-centric distance to the object. ⁽²⁾ Geo-centric distance to the object. ⁽³⁾ Magnitude measured in the acquisition images. ⁽⁴⁾ Magnitude measured in the averaged polarimetric frames. ⁽⁵⁾ Magnitude measured in the frames obtained with no polarimetric optics in. The last row refers to the brighntess at phase-angle 0 extrapolated with a linear best-fit. Blanks refer to frames where the image of 133P/Elst-Pizarro was contaminated by background objects. Values given in parenthesis should be considered as lower limits because obtained during a cloudy night.
