Assess whether `digest2` could be improved by accounting for particular sky areas

[TomWagg]

E.g. MBAs are not going to exist at the ecliptic poles, can we leverage that to improve the NEO score?

I was thinking about this and it is sort of backwards though, we want to rule out NEOs rather than rule out MBAs so perhaps we'll need to penalise scores for objects that are close to the ecliptic at that time?
