FITS files storing HEALpix RING data with 256 sides (pixel size of approximately 0.23°) and equatorial coordinates. More about the HEALpix pixeliztion scheme can be found on this page. These files can be opened by some FITS viewers, such as SAOImage DS9, as well as the healpy Python module.
Each file is approximately 3.1 MB in size:
Standard FITS images in a Mollweide projection with an approximate pixel size of 0.3° and equatorial coordinates. These files can be opened with various FITS viewers, like SAOImage DS9.
Each file is approximately 4.5 MB in size:
Our model of the low frequency radio sky (10 to 408 MHz) based on a principle component analysis of data at 10, 22, 40, 45, 50, 60, 70, 80, 408, and 1419 MHz. The 40, 50, 60, 70, and 80 MHz data come from our survey while the data for the other five frequencies are from:
The model can be downloaded from here as a 1.6 MB compressed tar file. The model is at a resolution of 5.0° and outputs HEALpix RING format text files with 64 sides. This gives the output models an approximate pixel size of 0.9°. Note: Most of the data going into the model is from the northern hemisphere so there may be additional uncertainities in the southern sky.
