A Mid‐Infrared Galaxy Atlas (MIGA)

A mid-infrared atlas of part of the Galactic plane ($75^\circ < l <148^\circ, b = \pm6^\circ$) has been constructed using HIRES processed infrareddata to provide a mid-infrared data set for the Canadian Galactic Plane Survey(CGPS). The addition of this data set to the CGPS will enable the study of theemission from the smallest components of interstellar dust at an angularresolution comparable to that of the radio, millimetre, and far-infrared datain the CGPS. The Mid-Infrared Galaxy Atlas (MIGA) is a mid-infrared (12 $\mu$mand 25 $\mu$m) counterpart to the far-infrared IRAS Galaxy Atlas (IGA), andconsists of resolution enhanced ($\sim 0.5'$ resolution) HIRES images alongwith ancillary maps. This paper describes the processing and characteristics ofthe atlas, the cross-beam simulation technique used to obtain high-resolutionratio maps, and future plans to extend both the IGA and MIGA.
