Major news No intention of accelerating the schedule. A list of items
suitable for risk reduction is being prepared by the JWST project and were briefly discussed by the SWG.
Instruments ok.

JWST Field of View Layout

Major news No intention of accelerating the schedule. A list of items
suitable for risk reduction is being prepared by the JWST project.
Instruments ok.
5
Major news No intention of accelerating the schedule. A list of items
suitable for risk reduction is being prepared by the JWST project.
Instruments ok. NIRCam : PIL is #1 risk reduction item. Tip-tilt focus mechanism.

Pick-off mirror andTip-tilt-focus mech.

Major news No intention of accelerating the schedule. A list of items
suitable for risk reduction is being prepared by the JWST project.
Instruments ok. NIRCam : PIL is #1 risk reduction item. Tip-tilt focus mechanism. NIRSpec: issue of pupil shear, potential loss of sensitivity in
NIRSpec 14-15% for 5% shear. Swiss company has produced cryogenic mechanical slit selector (backup to MEMS)
SWG will carry out trade study for 1/10/100 slits by June 04 MIRI: shear also an issue for coronagraph. Extra background at
>20m. FGS-TF: the SWG voted for uninterrupted wavelength coverage
up to 5 m. Survey Fields
8
Backgrounds – South galactic cap
Red = galactic dust, green = ecliptic declination, blue = selected fields (low dust, no bright stars, galaxies, radiosources)
9
Backgrounds – South galactic cap
Red = galactic dust, green = ecliptic declination, blue = existing fields (symbol size proportional to quality)

Major news – cont’d Discussion on need for some form of science parallels Long discussion about HST-JWST Legacy
JWST science may require visible imaging data How do we make sure those data are there when
needed? Full range of opinions (from do nothing to ask for a
fraction of HST time to be set aside). Too early for promising a JWST Quick look survey Agreement on doing nothing but informing the user
community about what JWST can and cannot do and where in the sky
Write a JWST Mini-handbook (?)
