• Online Asymmetry results

The asymmetries shown in this section are  online results, they should be consider as very preliminary
and showing nothing more than we were able to compute asymmetries, considering approximately all
the statistic sample from January 2003, the precision  ~ 2ppm  and the sign reverses with HWP insertion.
