Background regions of this shape should be chosen when there is no extended emission in the FOV, because OA-concentric regions are in general larger than source-concentric ones (thus offer better statisitics), yet sample everywhere approximately the same background level, because the value of the vignetting function is approximately the same at a given radius from the OA. fovbkgannulus =`no'....

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. ...

We present spatially resolved Spitzer Space Telescope imaging of the supergiant shell region of the M81 group dwarf galaxy IC 2574 obtained as part of the Spitzer Infrared Nearby Galaxies Survey. This region harbors one of the best nearby examples of a kinematically distinct H I shell, with an associated remnant stellar cluster; the shell is initiating sequential star formation as it interacts with the surrounding interstellar medium. ...

... Many of our new results favour a conal geometry for the arrangement of emission regions and allow accurate estimates of the emission heights and polar cap locations for the emission cones to be obtained. These results indicate that pulsar emission cones may be located at around half-way out the edge of the polar cap and at altitudes of a few hundred to a thousand kilometers above the neutron star surface. ...
