Hello everybody
Where is the people of that list?
Can yon help me?
I plot a horizontal sundial for a place at lat 22º15'S and lon 42º 7'W,
with longitude correction. I have calculated a declination line for july 15, but
the curve was strange in relation to the solstice line.
I'm asking if that angular dfference must be considered (added) to
the sun's altitude angles in order to get correct results?Thanks in advance Sergio
