OVRO-LWA Radio Maps

The sky maps are generated using the HEALPix sky pixelization scheme. The first file listed for each data product contains the data in its native HEALPix format. For the convenience of users who do not require the capabilities that HEALPix offers, we also provide the maps in two projected image formats: Mollweide and Zenith Equal Area (ZEA). These files contain the string "_mollweide" and "_zea" respectively, and may be displayed with standard astronomical display software such as DS9 and SAOImage.

Recommended download procedure for '.fits' or '.tar.gz' files:
right click on the file name and save. For more information on the use of Dataset IDs,
see the LAMBDA Products Overview.
