- The 3 solutions for pointing reconstruction (LAL, CEA, CRTBT) are converging. Currently, we use CRTBT in the data analysis (typically 5 arcmin global precision). A group (Alex. B., Eric A., JCH) should work on the intercomparison, improvements that can be made on all three methods (star detection, star catalog, pointing reconstruction, smoothing, use of gyros?).
- The most current version of archtoi on CVS works correctly: new feature it can generate galactic longitude and latitude TOI directly

- Full detail on the following reports can be found (sometimes in French) at http://weekly.archeops.org/Annex_20010424.txt
- CRTBT: Karine M. and Alain B. work on refurbishing the cryostat : leaks seem to be repaired and gas flows are nominal. All flight bolometers and thermometers stay at their flight position. But they are blind to study IV curves and noise properties. The plan is to cool down the cryostat tomorrow.
- LAL activities: work on Stellar Sensor pointing reconstruction
is near completion, work on optical cross-talk.
Optical beam FWHM during flight seem very close to the expected ones
(8 and 5 arcmin)!
