Goal

The goal of the present CLASS (data format and library) improvements is to provide a (much) less restrictive list of supported projections. This revision relies on the GREG projection engines which support:

With these improvements, a direct application is for example the native support of the rotated (i.e. scanning is not performed along azimuth or elevation) On-The-Fly mapping when observing at the telescope, using the azimuthal projection with a non-zero angle.
