Large-scale CMB anisotropies: wrinkles in the Galaxy rather than in time

Withdrawm. Public data of COBE-DMR are not perfectly subtracted from dipole. Therefore, the Galactic latitude dependence is affected by the remnants of the dipole and the results previously announced in this paper about this are not valid. Anyway, the suspect of a high Galactic contamination announced in another paper (Lopez-Corredoira 1999; A&A 346, 369) is still valid and to be considered. Thanks are given to Ted Bunn for helpful discussions which made me realize of the problem with the dipole.
