... About ATNF overview . ... Australia Telescope Steering Committee . ... LMC H II Region Luminosities versus . Observed Ionizing Stars . ... These values are compared to the observed H II region luminosities, yielding an estimate for the mean fraction of H-ionizing photons that escape the local nebulae in this sample. We formally estimate that, overall, 0-51% of the ionizing radiation escapes the local H II regions and is available to ionize the warm, ionized medium in the LMC. ...

... The low energy plasma composition spectrometer AMEI-2 is built to be able to find in the low energy range of the phase space (E, q, j) and separate the fluxes of the major ion species in the magnetotail - H+, He++, He+ and O+, and analyse their energy and angular distributions. ... Electrostatic angular scanning in one direction and the use of the spin of the satellite to sample the other angle give the ability to measure 2-D distributions for each ion specie several times per spin. ...
