Hi all,
I have been, for somewhat over 60 years now, been
using a 1904 Edition of Norie's Tables for Lunar Distance calculations and
general navigation purposes. This edition includes all necessary tables for
clearing the distance, including six place logarithmic tables to seconds of arc
for small angles, as well as the usual trig functions, haversine functions, and
all necessary altitude corrections for the Moon and Planets, both for true
and apparent - features which are not included in later
editions.
My problem is that I would like to replace these
tables, which are becoming dilapidated by age and wear associated usage, with
something equally comprehensive and handy, including possibly on disc. I have
several copies of Norie's Epitome, which include most of these tables, but do
not wish to expose these pubs to the wear and tear of frequent look-ups, as they
have been completely refurbished and rebound.
Does anyone out there have any suggestions. I have
just about exhausted my internet capabilities, which are limited to dial up at
present, but which otherwise have produced no concrete results as respects
logarithmic tables of any type. It does seem rather strange, to me at least,
that nobody has put tables such as this on disk or that no reprints have been
produced. I am also somewhat leery of the older available downloads, as the
tables included therein frequently contained rather subtle errors which
were not readily apparent at the time of printing.
Thanks in advance for any interest and
help.
Henry
