LAL activities: Reza: pipeline activities, time filtering instead of FFT filtering, first maps obtained with this method within the pipeline in collaboration with Cecile, Christophe... Stephane: continuation of the work on the extraction of the Fourier coefficient on the circles by a fit in the time domain fit of cosmological parameters with 3 parameters works fine now Alexandre: filtering of pointing data to extract wrong combinations and to propagate the pointing errors, which will give at the end the quality and accuracy of the method with Francois. Raphael: preparation of the electronics for optical leakage measurement within Archeops which will start on the 22nd with Francois continuation on the work on optical leakage measurement using Jupiter signal Sophie: continuation and cleaning of the code for measurement of optical leakage using Jupiter signal Comparison of Alain/Eric/Alexandre pointings with Jean Christophe
