Formulas make sense with the globe and ionosphere, not aware of any way to make it work in a disc-dome.

In depth explanation here: https://www.mezzacotta.net/100proofs/archives/552

The resonance is directly tied to the circumference of the earth and ionosphere.

Sideways Curve

On the flat disc model, east and west curve toward north. A train sufficiently long going on a track due east or west should therefore have a perceptible difference on one side (convex south side versus concave north side) if viewed from the end. Discers have to prove a different curve. In Canada there's a very long stretch of East to West highway that could be used for this. You could use a sufficiently large laser to see if the east to west highway deflects toward North, which would prove the curve required for the Azimuthal Equidistant Projection to represent an actual flat earth disc.

2019 Gyroscope Experiment Flat earthers buy $20K ring laser gyroscope Precision instrument Should be able to measure approximately 15 degree drift of Earth's motion. Measures exactly that haha.

Weather balloon during eclipse in the film shows no parallax whatsoever. Moon and sun very far away.

Eclipse paths are curved on a Mercator projection because of a curved earth. Eclipse shadows follow a curve.

Lunar Eclipse photos show a curve of whatever is between the Sun and Moon... Hmmmm...

The reason the night sky never changes over millennia is that the stars we can see through our atmosphere are also moving through the Galaxy with us. Barnard's star moves quite a bit per year at 6 light years. We can also calculate stellar parallax based on knowing our orbit diameter around the sun and making a few observations. This is how we know how far away some stars are.

Northern Hemisphere population is 6.96 billion people (87.0% of the earth's total human population). Southern Hemisphere population is 1.04 billion people (13% of the population).

There are lots of amateur videos of shooting stars going every direction, including towards the camera and upward from the horizon.
