Some of the recurring questions that we receive appear below in the FAQ. If you still don't find an answer to your question, please write to us at cade@irap.omp.eu.

At this time, CADE only delivers two-dimensional Healpix maps since the memory requirements for manipulating cubes in Healpix format are prohibitive. For historical reasons, the initial maps from spectral line surveys delivered by CADE were integrated intensity (moment-0) and column density maps for HI surveys. We are in the process of adding other 'moment' maps (e.g. peak brightness and velocity centroid maps) to the CADE database, and expanding the database to include more molecular line surveys.

If you are searching for a Healpix map of a two-dimensional quantity derived from a spectral line survey, don't hesitate to contact us cade@irap.omp.eu.
