In view of the fact that I mentioned the following project in both
Perl and Python Newsgroup notes and did not get any hostile responses I am
going to take a chance and mention it again in all three of these
Newsgroups. People posting responses might want to do that in just one
Newsgroup. I will check all three for responses for a few weeks.
This is the Web address for an interesting and apparently unique
computer program written using FORTRAN 77. As far as I am aware, it has
never been translated to newer language. There is a BASIC version that was
apparently written around the same time as the FORTRAN version.
What a number of us would like to do is obtain a copy of the program
that is written in a newer language so that we can then merge it with the
programs available through the following Web page. The new programs would
then be made available as freeware programs to researchers around the world.
This indirect link is being used in an effort to keep Web site related spam
to a minimum. I don't collect credits by having people visit that
(indirect) Web site.
If there are any programmers who might be interested in such a
translation effort then I would be interested in hearing from them.
Etgtab generates Solid Earth Tide and ocean tide data for any
location on or inside the planet. I am not aware of any other freeware
program that can do that.
SunGP available at that second Web site is the only freeware program
that I know about that generates what are sometimes referred to as subsolar
and sublunar types of data. The download code was written using True BASIC.
If you draw a line between the centers of the sun and the Earth then
the place where that line crosses the surface of the Earth is the subsolar
location. The sublunar location is the same type of thing. The SunGP
program code is also available in Perl code, but not through any Web sites.
