SkyView is now serving the data from the WISE All-Sky Data release. The main difference with the preliminary release is coverage on the ~40% of the sky that was missing in the earlier release. However the entire dataset has been reprocessed using updated calibrations and such.
We download WISE data from IRSA in large tiles, caching each tile so that we never have to download the same tile twice. It can take a while for WISE images to be generated if there has been no request in that region before, even when you are requesting only a very small region. It can easily take a minute or more to get the files we need to generate your image. As our cache grows you’ll be more likely to hit it and access should be much faster. Once data are in the cache it takes only a couple of seconds to generate a typical image.
The WISE data give us a view of the infrared sky comparable to the DSS optical images in the optical. We anticipate WISE being one of SkyView’s most popular surveys.
