\caption{\label{tab2}Polarization observations of comet C/2000 WM1 (LINEAR). Listed entries are
 date and time~(UT), total
 integration time~(IT) in seconds, filter, degree of polarization ($P$\%) , error in polarization~(Ep\%),
 position angle~($\theta$) in equatorial plane, magnitude (normalized with respect to magnitude
 at~4845~band),  and phase angle~($\alpha$)
 at the time of observations.  Magnitude values are not listed for 17th March 2002 as the
 photometric errors were larger than~10\%.}
