What Are the Ingress and Egress Times?

If the star would be completely uniformly bright, then when the planet transits, what we expect is from the moment it's ok. So in the case of no limb darkening, we have, in between this, in between these times, we have,. well, generally it would just be a flat curve, right? Because the brightness has dimmed by some factor. And assuming that the star is uniformly bright, it should dim by that same factor throughout the planet's transition, yeh. We receive less energy photons, actually, less of them, because it's like thinner, you dnow, i mean, like optical depth, less energy photon.
