<strong>SPINOR</strong>: Versatility<br />

� Plane-parallel, 1-component models to<br />

obtain averaged properties of the<br />

atmosphere<br />

� Multiple components (e.g. to take caree<br />

of scattered light, or unresolved<br />

features on the Sun). Allows for arbitraary<br />

number of magnetic or field-free<br />

components (turns out to be important,<br />

e.g. in flare observations, where we<br />

have seen 4-5 components).<br />

� Flux-tubes in total pressure equilibriumm<br />

with surroundings, at arbitrary<br />

inclination<br />

� in field-free (or weak-field surrounddings)<br />

� embedded in strong fields (e.g. sunnspot<br />

penumbra, or umbral dots)<br />

� includes the presence of multiple flux<br />

tubes along a ray when computing<br />

away from disk centre<br />

�� efficient computation of lines acros s jumps in atmospheric quantities<br />

� Integration over solar or stellar disk, inncluding<br />

solar/stellar rotation<br />

� molecular lines (S. ( Berdyugina) y g )<br />

� non-LTE (MULTI 2.2, not tested yet, reequires<br />

brave MULTI expert)<br />
