Mid-Infrared Galaxy Atlas (MIGA)

About the Atlas

MIGA is a mid-infrared (12 and 25 micron) atlas for part of the Galactic Plane (74 < l < 147 degrees; b = +/-6 degrees). It was created to provide a mid-infrared data set for the Canadian Galactic Plane Survey (CGPS). MIGA consists of specially processed HIRES (IRAS) images with a typical resolution of 0.5' along with ancillary maps.The data are useful for large-scale studies of diffuse infrared emission from polycyclic aromatic hydrocarbons (PAH's) and very small grains (VSG's) traced at 12 and 25 microns, respectively, and provide higher resolution images of compact sources as well. Corresponding 60 and 100 micron data are available through the IPAC IGA server.

Obtaining the Data

     MIGA data can be obtained in two different ways.  The MIGA server will allow you to preview the 20th iteration images for a given region and then download the images and ancillary files that you require. This service provides data for 1.4 degree square regions, on one degree centres, which can be mosaiced together seamlessly.

For the CGPS survey region, you can obtain large 5 degree square mosaics (of images and ancillary files) through the Canadian Astronomy Data Centre (data will be incrementally released in this format to go along with other CGPS data products).
