Hi Stephen,

Try returning the .sum() from within the main function. You've set the number of return entries to 1, but returned an iterable. So it only takes the first item from that iterable; this is actually part of the design. If you want to ensure that it gets an array (I do not think you want to do this, as it completely eliminates memory conservation) you can return (ct,) to ensure that it's an array inside an iterable.

But, I think you should be returning ct.sum() from _NumberOfStars.

You might try printing out what is fed into the combine function; I think what you really want to do is return (data["creation_time"] > 0).sum() in _NumberOfStars.  Inside _combNumberOfStars try printing both data and ct, as well, to see if it's an axis problem with the combine function.

It appears that for some reason only the first entry of each of the arrays from the grids is being fed into the combine function. The script http://paste.enzotools.org/show/1411/ outputs http://paste.enzotools.org/show/1412/. This sim has 297 grids, which is the size of the ct array in the combine function.

I'm confused...
