(c) the Moon is in Sect in a Night Chart irrespective of hemisphere and/or horizon

That's all good stuff.

This is a question often debated

'Ascendant' is the name given to the Eastern section of the Great Circle of the Horizon

If the Sun were visible on the Eastern Horizon then one would define that as Day
Nevertheless there are a number of definitions for both Sunrise and Sunset
- one of which is 'apparent sunrise/sunset'
- Due to atmospheric refraction, sunrise occurs shortly before the sun crosses above the horizon.
Light from the sun is bent, or refracted, as it enters earth's atmosphere.
This effect causes the apparent sunrise to be earlier than the actual sunrise.
Similarly, apparent sunset occurs slightly later than actual sunset.
However, it should be noted that
due to changes in air pressure, relative humidity, and other quantities
no one can predict the exact effects of atmospheric refraction on sunrise and sunset time:
this possible error increases with higher latitudes (closer to the poles).
Official times of Sunrise and Sunset may be found on various astronomical websites.

I don't see where that has anything to do with anything.

The positions of planets and points are derived from mathematical equations and not by looking.

The Sumerians and Akkadians and everyone else down to the 2nd Babylonian Empire had observatories to look at celestial phenomenon and predict eclipses. They had tables on clay tablets for the planets, Sun, Moon, constellations and stars to mathematically predict their locations in relation to Earth, including direct and retrograde motion of planets.

After the collapse of Mesopotamian civilization, you have the rise of Greek and Roman civilizations who were scientifically stupid.

The Arabs and Persians preserved a lot of the math, but the Greek, Roman and Medieval astrologers used astrolabes to visibly determine the position of the planets and luminaries.

They did have tables, but they were not mathematically derived, Instead they were rough approximations of where a planet should be based on the apparent speed of the planet. That's why there's a heavy emphasis on whether a planet is "slow" or "fast."

That's also why it's almost impossible to replicate a Medieval chart, because they were only guessing where the planets might be based on their apparent speed and not based on math.

Kepler rediscovered the math used by Mesopotamian civilizations and we use computers that factor in gravity and other considerations to know precisely where a planet is down to a few seconds of arc except for some of the outer planets where the accuracy is a few minutes of arc.

Anyway, "apparent position" is irrelevant and it's highly unlikely that someone's Ascendant would match the position of Sun to the exact minute or second of arc, so Sun is either above or below, and even if it came down to the exact second of arc, seconds are divided by 60 to obtain fractions of a second, and those would be divided by 60 and so on.
