Frank,
Yes, the true distances are
tabulated monthly.
And the six refraction tables are
made for every 10 degrees of
altitude and 10 degrees of latitude.
Alex.
P.S. If there is interest in a handy
source of star-to-star distances,
I can re-calculate the distances and
post them together with refraction tables.
