Hello all
I use AutoCAD and if I'm not wrong it can output files in both of
these formats.
Will let you know when i'm home in some hours.
Thanks

I think Andrew James' explanation about the sum of two symmetrical curves

the equation of time was determined. There is a good article on this in Sky

I think that it was not a choice to index to those dates but instead to
place the

the number of days that the EoT is negative. If the analemma is displaced this
balance cannot occur. I discuss this average on my
Luke, I really liked your clear explanation, but I think you meant to say
the ANALEMMA has two components, the EOT and the declination. The EOT is
not dependent upon the obliquity; we would still have it even if the axis
were perpendicular to the ecliptic. Luckily, both independent components
I don't really know, but I would think that the zero level is chosen so
that the total area of the EQT curve above the line matches that below the
line. This would make the annual mean of the EQT would be zero minutes.

Hi Bill,
If you mean to ask why the EoT was made to be zero at a given
set of dates, I think the answer is that it wasn't. One can't
arbitrarily make the EoT zero points (four of) synchronous to a set of
dates. The EoT has two components, obliquity (the tilt of our axis
relative to the
Hi Fritz,
The analemma is in essence just a graph of the EoT vs Declination, in
discussing the components of the EoT the analemma need not be mentioned,
the analemma is just another way of expressing the EoT. The dynamics of
the EoT define the shape of the analemma.
As regards
Hi All,
Here is a way to produce .prn plotter files directly from DeltaCad, or
any CAD Program.
These directions are for Windows98, but they should adapt to other
Windows versions.
Go to Control Panel | Printers.
Select Add Printer, and follow the Wizard to install a Local
Printer.
