It looks to me like the HEALpix rendering works within the context of the camera being somewhere inside the of the computational domain. For a light cone, it would need to be able to operate as it it were very far away from the domain where the entire volume subtends a very small solid angle. I'm not sure this is possible in the current framework. Can someone more familiar with the HEALpix render comment on this?

Hi,

I'm looking at the light cone and all sky examples, and I'm wondering how much effort (in human units, not computer time) is required to produce an all sky map based on the "shift and stack" method used for light cone generation. Naively, the answer seems to be based on whether or not the light cone generator projection function could use the HEALpix camera.

Is there a simple way to create an all sky map combining several data sets?

Thanks,
Rick
