It might be easier to just implement the formula for the memory usage
than to hardcode these values, if we just need a rough estimate.

I think such an estimate isn't actually required, because the maximum
memory usage I see is 120 MB with the Tycho-2 deep catalog, whereas it
was 70 MB earlier (with Hipparcos), but it would be a very nice
feature that IMO will be well appreciated.

In any case, I will start working on computing the memory usage. Let
me know if you think otherwise.
