The name "angulardimdist" is quite anti-intuitive, since the angular diameter
distance has nothing to do with "dimensions"; but it is related  to a diameter
(one way of defining it, which presumably explains the name, is the Euclidean
static space distance that an extragalactic object would be at if it's angular
diameter in radians were to be used to infer the object's physical (proper)
size in the tangential direction).

I've proposed a commit at d6b4823f [1], which works for me, to correct from
'dim' to 'diam' in the four places I found where it occurs.
