On screens 4 and 5, the ' and ° symbols are not interchangeable. 1° = 60'
Sunrise and sunset are when the upper limb of the Sun appears to cross the horizon. A geometric altitude of -50' (-0.83°) is conventionally used to account for the angular width of the Sun and atmospheric refraction.

This one was more of a programming convenience. But, on a related note, before this project I was always confused when I saw degrees mixed with minutes & seconds when I looked at maps and such. Thankfully that mystery has been solved.

TIL. I'll try to incorporate this change in the next edit. Thanks for the feedback!
