  2. JWST cycle 1 programs • S. Zeegers: 12 sightlines (ID:2183)

    – Galactic plane, 3 different regions • M. Decleir: 9 sightlines (ID:2459) – All also have HST UV depletions (current cycle), FUSE H2, IUE HI, FUSE/IUE extinctions • Both use NIRCam TSO grism and MIRI MRS – cover 2.4-28 microns – measure the 3.4 micron HAC feature and 10 & 20 micron silicate features (and any other features) – measure the continuum extinction over the full range
