... Only the HST and STIS have the right combination of spatial and spectral resolution to adequately reject the contaminating light from the Orion Nebula itself and allow clear determination of the emission coming from the young stellar object. ...
... 2) A determination of the 3D structure of the nebula, based on the ionization echo that will sweep out into the nebula, causing each individual knot to develop strong H-alpha emission when first illuminated by the nova. ...

... 1.16 Completed WF/PC-2 6353 (A Snapshot Emission Line Imaging Survey = of Very Low Excitation Planetary Nebulas) The WF/PC-2 was used to make snapshot observations as part to an = emission line survey of the very low excitation planetary nebula = PK045 ...
... Even assuming the nebula evenly illuminates the full 28 arcseconds of the long slit, we are well below the global absolute and linearity limits, since the flux from the nebula is concentrated in the C IV emission line. ...
